Due to a previous issue I am trying to do the following
mixin template A()
{
mixin((function () => "int x;")() );
}
the problem is that the compiler will not let me use the
delegate because it has no this context. Of course the whole
point here is that the delegate will never be used at runtime
since it is used in the mixin(which is purely compile time).
It should work(there is no reason it shouldn't) yet it doesn't.
The goal is that I do not want to create a function outside
the mixin to use because it will be included in the context of
the template mixin. e.g.,
mixin template A()
{
string B() { return "int x;"; }
mixin(B()); // still doesn't work but if it did B would be
inserted in the context of the template. e.g., if used in a
class the class would then have a method named B in it, hence
the use of the lambda.
}
There shouldn't be a context pointer at all as you specified
that it's a function, not a delegate. Function literals don't
have context pointers as far as I know. Did you try:
mixin((function () { return "int x;" })());
Just to be sure?
Thanks, I thought I did try that(that was the first thing I tried
I thought). Seems to be working though.
