Bad syntax highlighting using < inside regex

[anquegi]

While testing regexes using emacs I found the following:

my $m = rx /\d ** 2 <?{ 1 <= $/ <= 12 }>/;

then all the text is colored like inside a string, I need to finish the line with #>> in order to finish the two opened <
I added the captures to better view of the problem:

Hello,

I encountered a very similar problem: in my case, this happens in strings that start with the <-character:

workaround: you can add "# '>'"-comment snippets in your Raku code.

This is in emacs 26.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.5) of 2021-01-31, modified by Debian (the debian package version is 1:26.1+1-3.2+deb10u2). raku-mode is manually cloned: I'm on commit 4ee9045.

Just encountered this as well, glad to know I'm not the only one.

The < in the when block and the > in atom => $x are creating the string context, somehow
