If no .params are given, no args checking is done on sub invocation. From
the original:

2 sample patches to achieve this (both of which are declared to fail) are
attached to the original ticket. Neither apply cleanly to trunk.
There is a question, however, as to whether or not the existing behavior
is desirable - should we always check args? should we always check except
for :main? (should we check for :main too and suggest that the programmer
use .param args :slurpy to avoid any issues?)
There's a test already committed in t/op/calling.t
