Trying to do some tricky stuff but I can't seem to get the value
of a type(enum in my case, but must work in general).
Basically, given a type T or an alias T(alias preferred), I'd
like to be able to get the "default value" of that type.
e.g.,
if it is an enum and I have an alias to a member, instead of
(Enum)3 I want 3.
if it is a member field, I want the default value.
if it is a function pointer, the address(probably 0, but
whatever).
Basically a sort of generic "getValue" that attempts to get the
CT value of any type, if it exists. (obviously the value of class
is meaningless, so returns ""... class isn't even a type, but can
still query).
In fact, I'd like to also naturally resolve the value back in to
the expression that created it.
e.g.,
(Enum)3 -> Enum.ThirdEntry
