__FUNCTION__ does not return anything when used in templates.
For debugging purposes I sometimes use pragma(msg,

template assigned an enum)
It can be relatively trivial or incredibly difficult, depending
on exact string output for a given template you want get and
set of template types supported.
I just want the current template name in the current scope. I
know it seems trivial but it would help me reduce boilerplate
code. I'm using it to debug and use the template name as a way to
turn on debugging for specific templates if I need to analyze
their behavior(lots of code generating templates that may have
bugs).
A similar feature would end up being needed for functions when I
log functions debug output.
With such a function I can just copy and paste the line to
display the output rather than copy paste modify(replace the old
template name with the new).
I don't need the template name of a template that called it...
that is different, possibly useful but not required.
void f()
{
pragma(msg, __FUNCTION__);
}
template t()
{
pragma(msg, __FUNCTION__);
}
void main(string[] argv)
{
readln();
}
the function displays main.f. The template displays nothing. I'd
prefer it to display main.t! or something unique so I can use it
as a hash.
