q, qq and qx here-documents (for consistency with qt here-docs)

[Philippe Bruhat (BooK)]

Hi,

The current version of PPC 0019 proposes a here-doc version of `qt`:

> To provide a heredoc version of qt, this:
>
> <<qt{END} TEXT END
>
> will apply qt-like interpolation to TEXT.

Once this is implemented, a nice addition (mostly for consistency and
cuteness) would be to add support for `<<q` (single quotes here-doc),
`<<qq` (double quotes here-doc) and `<<qx` (backticks here-doc).

I note that perlop says:

Adding support for q(), qq() and qx() in place of '', "" and `` to define
end-of-string identifiers (for consistency with the addition of qt() there)
would behave the same as the regular quotes already do in this case, with
the only interpolation being for backslashing the quoting character.

Those seem like simple enough additions to add alongsite the qt
heredocs yes.

Currently looking at the schedule of things, I don't imagine I'm going
to get any time to work on qt now before v5.40 release so that'll have
to be a thing for v5.42 - or will we call it v7? I can always hope ;)
