Walter and I are looking at ways to implement it. Here's a
baseline without static foreach - a "trace" function that
prints function calls before they are made:

If the function is overloaded, that won't work. In such cases,
static foreach might be helpful. Here's code from the cycle "I
have a dream":

I'm trying to collect together motivating examples and to
figure out the semantics of the feature.

How will scoping work? Similar to mixin templates?
It would be nice together with this feature to be able to mixin
identifiers:
static foreach (ident; ["foo", "bar"])
{
auto mixin(ident)()
{
// code for foo/bar
}
}
Otherwise, other than overloads and template instantiations this
won't be much better then generating code strings with CTFE...
