[14:28:22] <lizmat> r: sub a ( $a is copy ) { $a=5 }; a(1)
[14:28:24] <+camelia> rakudo 0e206e: OUTPUT«Cannot modify an immutable
value in block at /tmp/Dmc8P4X3n2:1»
While checking into this at the PLPW, it appears that this is an optimization
problem. If rakudo is run with --optimize=0, this does not occur.
Initial investigation points at src/vm/parrot/guts/bind.c, line 1104, where
some optimization magic apparently is making the wrong decision.
This seems to be up jnthn's alley :-)
