This is because of the change of handling of recent perl for
braces in regular expression.
Well, I think you are using enumerate package. Current l2h may
have several problem for the handling of enumerate package.
1) Option 'A' of enumerate environment uses "alph", not "Alph"
(it is a bug of sub Alph(): -> )
2) "eval($enum{..." string is included in regular expressions
(we can avoid it to modify
if ($standard_label) {
$item =~ s/(\\labelitem$rlevel|$standard_label)/$enum_label/g
to
if ($standard_label && $standard_label !~ /eval\(/) {
$item =~ s/(\\labelitem$rlevel|$standard_label)/$enum_label/g
)
3) The option are analyzed by the regex "$enum_label_rx", which
includes braces { and }. But the braces in options string are
modified to <<[n]>> before using "$enum_label_rx". Then, the
escape by {, } are not recognized correctly.
4) The regex "$enum_label_rx" supposes that the option must have
a character [AaIi1].
I will consider the solution for problems 3) and 4).

Re: [l2h] l2h new error
Hi,
I tried to fix this bug.
It seems that eval is the problem inside the regex
Instead of doing that I am evaluating that expresion vefore just to reduce
the complexity of it.
my $std_label = "\"$label_fields[0]\"" .
eval($enum{"theenum$rlevel"}). ".\"$label_fields[$#label_fields]\"";
# print "$std_label\n";
if ($standard_label) {
$item =~ s/(\\labelitem$rlevel|$std_label)/$enum_label/g;
} else {
$item =~ s/(\\labelitem$rlevel)/$enum_label/g;
}
Saludos
