should it recognize =finish?

[stuart-little]

As far as I can tell, the closest Raku semantic cousin to Perl's __DATA__ marker is =finish. As per the REPL:

> __DATA__
===SORRY!=== Error while compiling:
Unsupported use of __DATA__ as start of data.  In Raku please use: the
=finish pod marker and $=finish to read.
------> __DATA__⏏<EOL>

When I type __DATA__ in a *.pl file I'm editing in emacs, the item is recognized and the color and behavior of the text following it is identical to that of a multi-line comment (no special indentation, recognized keywords, etc.).

I think it would be helpful to have something analogous in raku-mode whenever =finish is encountered. Currently, it doesn't have much of an effect at all: indentation stays in place, keywords that I might place accidentally in the $=finish text are still colorized, etc.

Would this make for a good enhancement of the mode?
