It is my understanding that that is correct. I am a novice at mod_perl, but
your experience would seem to match up with my understanding of the Guide.
Local would scope it to within the enclosing block; so you could scope a
variable within a bare block so that it would be local to you package, but
shareable between subs.
# $/ equals default, global value
{
local $/ = undef;
sub { ... # $/ equals undef }
sub { ... # $/ equals undef }
sub { local $/ = "\n\n"; # localized value for sub }
# $/ back to undef
}
# $/ back to default, global value
