How about:
1. reverting the
is(typeof(foo) P == function)
to the old 2.059 behavior of being a type tuple only.
2. adding a parameters to traits,

I have a patch for this specific case, but it's a kludge, not a general
solution.
The problem is that the context of the typeof(x) is not the context of

Can you post an example of why you need this? Perhaps there's another way.
It's difficult for me to extract a concrete example (a very large

Ok, I suggest abandoning this .stringof proposal as unworkable. Instead, how
about a traits that gives the default arguments as an expression tuple?

Note that the default argument can be retrieved using something like:
PT[1] getDefault(PT a) { return a[1]; }

Or better:
PT[1] getDefault(PT[1..2] a) { return a[0]; }
An example:

Can you please verify the behavior you are seeing?
Sorry, that should have a typeof():
