Are you sure?  I think if one would put the same breaks-CPerl content
inside a here-doc, CPerl would slow down as well.  AFAIK, here-docs
are still facified; the result is just ignored.

Hmm, on the other hand, if it is syntaxification which is slowed down,
then yes - it should not be a lot of problem to skip stuff after
__DATA__, since CPerl does syntaxification in one pass.

Eh???  AFAIK, it ends with EOF period.

  (The code to parse <DATA> may have some special logic to find your
   __X__; but it may look for whatever it wants as well...)
