I'm sorry, I skipped a step here. The compiler doesn't look into
the mixin string until after it calls mixin, so technically it
goes:
static foreach ->
mixin("void print" ~ 'A' ~ "(int a) {

At first I was very confused that this example even worked. Why
does `ch` get expanded in the call to writeln? It is part of
the mixed in string, so why does the string not simply include
"writeln(ch, ...)" on every iteration?

You can't. Best you can do is write the function separately and
then mixin an alias for it with the other name.
void main()
{
enum letters = ['A', 'B', 'C'];
// normal

I think you can't do a partial statement in a mixin.
But

Hi,
I want to do something like this:
void main()
{
enum letters = ['A', 'B', 'C'];
static foreach(ch; letter)
{
void mixin("print" ~ ch)(uint i)
{
writeln(ch, " - ", i);
}
}
printB(6);
}
Create some function in loop and use it.
