I'd like advice on how to handle method invocations that include

method() {do something}
The idea is to turn the block into a closure pmc. The problem is how
to pass this to the method, so that it knows that it's a special
block parameter. Particularly in a way so that a language which
doesn't know about blocks can still call Ruby code.
Can't you just compile the code like this:
new_pad 0
newsub $clos, .Closure, _do_something
method($clos)
...
.sub _do_something
new_pad -1
...
and pass the closure as additional argument to the method?
My main worry with this approach is how it would interact with slurpy
args. I mean if method is defined as
def method(*args)
...
end
how do I make sure that $clos doesn't become part of args?
