For regular runtime parameters, there's ParameterTypeTuple. How 
would I write an equivalent template for template parameters? i.e.

     void fun(Foo foo, Bar bar)() {}

     alias types = CtParameterTypeTuple!fun; //TypeTuple!(Foo, Bar)

I've tried but my is expression kung fu was weak.

There is http://dlang.org/phobos/std_traits.html#TemplateArgsOf, 
but it only
works with an instantiated template.

actually, you can't. uninstantiated template cannot be processed by=20
anything, as it's not semanticed yet. and to semantic it, you have to=20
instantiate it.=

The way I wrote it, no. But if they all have default values, then
yes:

TemplateArgsOf!(fun!())

Unfortunately this is not implemented yet. But there's a pull request [1].
