These are the terms sent out in the proposal last week and described in
StoredAndComputedVariables.rst.
variable
anything declared with 'var'
member variable
a variable inside a nominal type (may be an instance variable or not)
property
another term for "member variable"
computed variable
a variable with a custom getter or setter
stored variable
a variable with backing storage; any non-computed variable
These terms pre-exist in SIL and IRGen, so I only attempted to solidify
their definitions. Other than the use of "field" for "tuple element",
none of these should be exposed to users.
field
a tuple element, or
the underlying storage for a stored variable in a struct or class
physical
describes an entity whose value can be accessed directly
logical
describes an entity whose value must be accessed through some accessor

- suppress error from type checker (missing return value in a non-void
function) if the source had an expression, but had a parse error;
- mark the diagnostic as PointsToFirstBadToken.

Our recovery is better now, and we don't skip that much. Actually, even if we
would stop at code completion token during recovery, completion results would
be something very generic anyway (because there is no interesting parser state
to observe), and these results can be produced as a fallback separately (not
implemented).

value expression and the type checker will complain anyway.
Instead, recover by unwrapping the BraceStmt that is contained inside, and
produce a specialized diagnostic.
Swift SVN r7680
This increases the amount of noise in diagnostics. But we did not get these
diagnostics before because we were just skipping these brace statements. We
shoud improve recovery in parsing of whatever declaration that precedes the
brace statement so that it is picked up as a body of that declaration.
Swift SVN r7679
Now we make the desicion to delay parsing if the parsed production contained a
code completion token, not if we just stopped at the code completion token.
Swift SVN r7442
But the implementation of expression parsing still does not propagate the code
completion bits because it uses NullablePtr for results.
Swift SVN r7425
This allows the parser to recover, create an AST node, return it to the caller
*and* signal the caller that there was an error to trigger recovery in the
caller. Until now the error was signalled with a nullptr result (any non-null
result was considered a success and no recovery was done in that case).
This also allows us to signal the caller if there was a code completion token
inside the production we tried to parse to trigger delayed parsing in the
caller while doing recovery in the callee. Until now we could not do recovery
in the callee so that the caller could find the code completion token.
Right now we don't take any advantage of these features. This commit just
replaces some uses of NullablePtr with ParserResult.
Swift SVN r7332
This allows us to show generic parameters in:
struct S<T> {
func f(a: #^A^#
}
And show the type Z in:
struct S {
func f(a: #^A^#
typealias Z = Int
}
Swift SVN r7216
Constructor delegation in parser was useless, because the code was split
between the constructors arbitrarily.
There was no need to pass down IsMainModule because the parser could figure
that out on its own. Also rename it to allowTopLevelCode() to better describe
what it actually affects.
