Improved detection of trailing unbalanced curlies in decomment() (thanks Albert)
Added (?&PerlEntireDocument) rule
BACKWARDS INCOMPATIBLE CHANGE: PPR::decomment() now retains all newlines from any comments, POD, etc. that it removes. This does not change the meaning or behaviour of the decommented source code in any way, but ensures that consistent line numbers are preserved through the operation. (thanks Albert)
