Basically, maketext was compiling +bracket notation into functions, but neglected to escape backslashes +inside the content or die on fully-qualified method names when +generating the code. This change escapes all such backslashes and dies +when a method name with a colon or apostrophe is specified. +--- + AUTHORS | 1 + + dist/Locale-Maketext/lib/Locale/Maketext.pm | 24 ++++++++---------------- + 2 files changed, 9 insertions(+), 16 deletions(-) + +diff --git a/dist/Locale-Maketext/lib/Locale/Maketext.pm b/dist/Locale-Maketext/lib/Locale/Maketext.pm +index 4822027..63e5fba 100644 +--- a/dist/Locale-Maketext/lib/Locale/Maketext.pm ++++ b/dist/Locale-Maketext/lib/Locale/Maketext.pm +@@ -625,21 +625,9 @@ sub _compile { + # 0-length method name means to just interpolate: + push @code, ' ('; + } +- elsif($m =~ /^\w+(?:\:\:\w+)*$/s +- and $m !~ m/(?:^|\:)\d/s +- # exclude starting a (sub)package or symbol with a digit ++ elsif($m =~ /^\w+$/s ++ # exclude anything fancy, especially fully-qualified module names + ) { +- # Yes, it even supports the demented (and undocumented?) +- # $obj->Foo::bar(...) syntax. +- $target->_die_pointing( +- $string_to_compile, q{Can't use "SUPER::" in a bracket-group method}, +- 2 + length($c[-1]) +- ) +- if $m =~ m/^SUPER::/s; +- # Because for SUPER:: to work, we'd have to compile this into +- # the right package, and that seems just not worth the bother, +- # unless someone convinces me otherwise. +- + push @code, ' $_[0]->' . $m .
