Given a string (or String),
return a single stack that contains the work to be done.
This stack can then be passed to
__expression_interpret to actually invoke the items on the stack.
Uses the standard two arg return - if
TCL_ERROR is returned,
then we return our error information back up the chain.
If we return
then we're returning the invokable PMC.
Given a pmc containing the tcl-style call level, return an int-like pmc indicating the parrot-style level, and an integer with a boolean 0/1 - was this a valid tcl-style level, or did we get this value as a default?
