EC#: New `?>` operator causes parser errors in code like `X<T?>` #140

Open qwertie opened 3 years ago

It needs to be parsed as two tokens, not one. Example:

static ThreadLocalVariable<IFoo?> _default = new ThreadLocalVariable<IFoo?>(null); // ERRORS

Workaround:

static ThreadLocalVariable<IFoo? > _default = new ThreadLocalVariable<IFoo? >(null);

Note: this is a separate and more widespread issue than #133

@qwertie Language complexity to blame :/
