Summary: MAL command resolution: BAT signatures with :any
Initial Comment:
not knowing about the MAL pattern
bbp.bind(:str) :bat[any::1,any::2]
I tried the MAL command
bat5.load(:str) :bat[any::1,any::2]
though the implementation and signature of that command appear to be fully
correct, bat5.load() always give a type mismatch error whatever you do.
So, the problem is not so much bat5.load(), but (I assume) the function
resolution of any MAL command that has :any::x or BAT[:any::x,:any::y] in its
signature.

I was providing the correct types. Did you try it?

MAL requires that all arguments are strongly typed.
you have to type the result variable upfront, e.g.
b:bat[:oid,:str]:= bat.load("mybat");
