How can I create a default type so that I can call it like
myclass.myfunc()?
Can't do that. Best you can do is myclass!().myfunc, then it will
use the default type (write it is (T = int) bw) but you have to
put in the !() to actually use the template.
There's a patch for the compiler to change this, but the compiler
devs are split on if it is actually a good idea or not, because
of a few cases, one I remember is:
template foo(T = int) {}
alias foo bar; // is bar == foo or is bar == foo!int ?
bar!float; // legal or illegal? It is legal today, but with the
patch it becomes questionable
