So what will perl6's "" parser do if it is presented with what appears to
be a $() interpolation sequence inside some other double quoting
construction?
1: Proceed silently (so treating "\c[$(call_a_func())]" as a request for
the character literally named '$(call_a_func())'), potentially returning
whatever warnings fall out of that second stage
2: Issue a nesting warning when it finds something that seems to be an
interpolative construction occurring within another construction, but
otherwise carry on
3: Treat it as a syntax error
I suspect that the answer is "yes" - ie all of the above, with a warning on
nesting interpolative constructions, which can be made fatal, and can be made
silent.
