Hey guys,
I've found a problem that occurred since DMD 2.034:
When I've created a dynamic array like
string[] a;
and I want to assign something via the index of this array
a[0]=Test;
DMD says the array isn't mutable...even if these are normal types like int or
char.

Ah yeah, thanks, that was it.
Don't get the reason for that syntax.
I think it has something to do with uniformity inside templates or
something.

does this make sense, or would it make more sense as an error for not

Doh. It looks like

I don't know where you're getting that grammar. Is that from the D spec?
um, yeah.
Declaration:
You mean how the compiler rejects alias const int x; but not alias
static int x;? That is strange..
I want to know why
alias static int x;
is allowed in the first place
From the specs:
It is not an error to have const module variable declarations without
initializers if there is no constructor. This is to support the practice
of having modules serve only as declarations that are not linked in, the
implementation of it will be in another module that is linked in.
I'm tired and witless just now, but I can't think of any reason why
assert should be an expression and not a statement.
Any clues?
when is symbol shadowing permitted/forbidden?
It appears that it is only forbidden in multiple levels of statements,
but not in multiple levels of declDefs

This is a classic C thing. The short explanation is that a switch is a

Why is it allowed?
