I just noticed in D1 that the values for the cases in a switch must

Is
this
also true in D2? If so, I don't suppose we could get that changed
before the
book? It's a real PITA for dynamic code.
I wish they'd get over it.
import tools.base;
...
mixin(
ReplaceConcat!(2, "if (x == #) { ! } else",
"#", "!",
"A", "handleTheACase; ",
"B", "handleTheBCase; ",
"C", "handleTheCCase; "
)
~ " assert(false); "
);
Now if only D templates handled variadic alias parameters,
I want this (for other reasons).
and my idea
of mixin templates, we could instead have this syntax:
int n;
SwitchCase!( n,
A, handleA(),
B, handleB(),
C, handleC(),
assert( false )
);
I think you ca get this to work right now:
SwitchCase!(n).
Case!(A, handleA).
Case!(B, handleB).
Case!(C, handleC).
DefaultFail!();
