Unable to instantiate template with same name as function

Why is it not possible for the overload to happen? After all, the compiler 
should be able to identify which to use by seeing whether it is followed by 
! or (), no?

OK but say I have a function which returns an array. If I use enum to CTFE 
its result, then it is repeatedly included explicitly in all places it is 
used, thereby using more memory. So I want to do:

string s = ta!"s";

Obviously, I can still do the different name approach, so it brings us back 
to the question as to why the name can't be re-used.
