One thing that I miss sometimes when doing meta programming is being
able to hide that a function should be called with mixin.
For example (pardon my lack of creativity):
// Instead of
string declare_a() {
return "int a;"
}
int func() {
mixin(declare_a);
return a;
}
// Could we have?
mixin declare_a() {
return "int a;";
}
int func() {
declare_a;
return a;
}
I think this could be useful when one is creating Idiom and Patterns,
you could hide implementations details.
You can do this:
mixin template declare_a()
{
int a;
}
int func()
{
mixin declare_a;
return a;
}
but there is no way to exclude mixin before calling declare_a, there is
a good reason for that (it is really important to be able to tell when
you use mixin and when not)
