There's other fallout from the same thing that causes this:
$ perl6 -e'say qx[ echo [ echo abcd ] ]'
/bin/sh: line 1: ]: command not found
[abcd
$ echo [ echo abcd ]
[ echo abcd ]
This happens because postprocess_* is called on each <nibble>. Something like
"< < a b c > >" is parsed as:
"<" ← <starter>
" " ← .
"<" ← <starter>
" a b c " ← <nibbler>
">" ← <stopper>
" " ← .
">" ← <stopper>
The inside <nibbler> post-processes " a b c ", turning it into ("a","b","c").
The outer <nibbler> subsequently turns that into "<"~("a","b","c")~">" (or "<a
b c>"), and post-processes that into "<a b c>". A similar process happens for
qx[].
