At the latest release, 0.000021 <https://metacpan.org/release/PPR>, one of
the changes you added looked like this:
@@ -66,7 +66,7 @@ our $GRAMMAR = qr{
(?<PerlDocument> (?<PerlStdDocument>
\x{FEFF}?+ # Optional BOM marker
- (?&PerlStatementSequence)?+
+ (?&PerlStatementSequence)
)) # End of rule
(?<PerlStatementSequence> (?<PerlStdStatementSequence>
That made remember that PerlStatementSequence and PerlPodSequence match
sequences of zero or more "things", and thus may get away without the ?+
quantifier (which is implied). If that holds true, you may consider the
attached patch that applies this simplification throughout the code.
