Support `int*[0].init`

[ntrel]

Since 2.102.2 (found with run.dlang.org), the following is valid:

	enum E : int*[0] { a = int*[0].init }

dfix with libdparse updated to 0.25.1 causes these errors for the above line, on the * token:

/home/nick/dr/src/core/internal/traits.d(652:35)[error]: Primary expression expected
/home/nick/dr/src/core/internal/traits.d(652:39)[error]: `,` or `}` expected (found token `.`)
