Regular expression breaks syntax highlighting

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.69.0
• OS Version: Debian unstable, Linux 5.18.0

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 other valid character)

Or add = to the list of allowed characters
