#   Methods, submethods, macros, rules, and pointy subs all  
#   bind their first argument to C<$_>; ordinary subs declare
#   a lexical C<$_> but leave it undefined.   

# Do pointy subs send along a declared param?

# Hm. PIL2JS currently dies here (&statement_control:<for> passes one argument
# to the block, but the block doesn't expect any arguments). Is PIL2JS correct?


# Do pointy subs send along an implicit param even when a param is declared
# (See the quote from A06 above)
for @list -> $letter { is( $_ ,'a' ) }
