[perl #55586] [BUG] Parrot no longer uses HLL_map types?

[James Keenan via RT]

I may be doing something wrong, but now it seems that it doesn't compile
at all:

[li11-226:parrot] 525 $ cat tclsh.pir 
.HLL 'Tcl', 'tcl_group'

.sub main :main
.param pmc argv
foo(argv)
.end

.sub foo
.param pmc args :slurpy
$S0 = typeof args
say $S0
.end

# Local Variables:
#   mode: pir
#   fill-column: 100
# End:
# vim: expandtab shiftwidth=4 ft=pir:

[li11-226:parrot] 526 $ ./parrot tclsh.pir 
error:imcc:syntax error, unexpected COMMA, expecting '\n' (',')
        in file 'tclsh.pir' line 1
