Now, if rate qualifiers aren't used to specify otherwise, varying
pointers point to uniform types by default. As before, uniform
pointers point to varying types by default.
float *foo; // varying pointer to uniform float
float * uniform foo; // uniform pointer to varying float
These defaults seem to require the least amount of explicit
uniform/varying qualifiers for most common cases, though TBD if it
would be easier to have a single rule that e.g. the pointed-to type
is always uniform by default.
Allow atomic types to be initialized with single-element expression lists:
int x = { 5 };
Issue an error if a storage class is provided with a function parameter.
Issue an error if two members of a struct have the same name.
Issue an error on trying to assign to a struct with a const member, even if
the struct itself isn't const.
Issue an error if a function is redefined.
Issue an error if a function overload is declared that differs only in return
type from a previously-declared function.
Issue an error if "inline" or "task" qualifiers are used outside of function
declarations.
Allow trailing ',' at the end of enumerator lists.
Multiple tests for all of the above.
