Regular expression breaks syntax highlighting

[alexr00]

Regular expression breaks syntax highlighting for remainder of the file. The offending line (perl) is here:

if ((($var, $val) = /^\s*([_a-zA-Z0-9]+)\s*=\s*(.*)/) != 2) {

The *'s after each \s seem to be relevant; deleting one fixes the formatting (but deleting two breaks it again).

Steps to Reproduce:

1. Do above
2. See error

Looking at the highlighter code It looks like regex strings can only come after (, {, ~, &, |, if, unless or a newline. in your example, the regex is after a =, which isn't supported

As a temp work around, you can just surround the regex with brackets (or any of the other valid character)

Or add = to the list of allowed characters https://github.com/textmate/perl.tmbundle/blob/a85927a902d6e5d7805f56a653f324d34dfad53a/Syntaxes/Perl.plist#L1174

Should make report to: https://github.com/textmate/perl.tmbundle

Huh! Thank you, that is very helpful!
