Y'all know if we write this:
static foreach(foo; [1,2,3]) {
int blargh = foo;
}
we get:
e2.d(2): Error: variable e2.__anonymous.blargh conflicts with variable
e2.__anonymous.blargh at e2.d(2)
e2.d(2): Error: variable e2.__anonymous.blargh conflicts with variable
e2.__anonymous.blargh at e2.d(2)
because it expands to
int blargh = 1;
int blargh = 2;
int blargh = 3;
all in the same scope. This makes static foreach of fairly little value
to me - most times I have considered using it, I end up just using plain
old string mixin instead so i can generate names for the declarations.

See "limitations" section of DIP 1010 for my thoughts:

(Mixin identifiers are among them. You might also like __local
declarations.)
