The error message from parrot when there is a spelling mismatch between
a function call and the function's actual declaration is accurate but
confusing:
*****
$ cat > foob.pir
.sub main :main
foo()
.end
.sub foob
print "Hello\n"
.end
$ ./parrot foob.pir
Null PMC access in invoke()
current instr.: 'main' pc 7 (foob.pir:2)
*****
Of course, once you've seen this error message once or twice, you won't
soon forget the diagnosis. For the sake of beginners however it would
be nice to add a hint to the message, for example:
"Null PMC access in invoke(); misspelled sub name in function call?"
And a similar hint for method calls as well, I suppose.
