Just checking ... there's still no way to construct symbols (maybe 
tokens is the right word?) at compile time is there?

For instance if I want to have something like

template funcs(char[] suffix) {



}

resulting in

   funcs!("f").function1()

being equivalent to the call

   function1f()

There's still no way to do that, right?
Any good workarounds?
(In this case I'd actually like to take 3 strings and paste em together 
like that to make a function name).

Nope. But if someone is counting votes, I'd like that functionality as well.

not directly but checkout my dparse lib (dource -> projects -> scrapple -> 
dparse) it uses template specializations to generate and refer to custom 
symbol names. It's limited (no forward reference and everything must be
declared 
in the same scope) but I works for the most part.

Allowing template specializations to overload from different scopes and
allowing 
lazy lookup or forward referencing of specializations* would make this vary 
powerful. 

* IIRC these aren't in the spec but DMD seems to handle them some way
