Ligature request: ::=

[GeertBosch]

#BNF notation is often used to indicate syntax descriptions:

<expr> ::= <term>|<expr><addop><term>

We have a nice ligatures for :=, but ::= really is inconsistent in comparison, as the :: ligature visually breaks up ::= into :: and = parts. They should really be like the := ligature, but with the left two dots repeated to form a square, and probably the equals sign part extended a bit more.

This would look better something like:

Thanks for the super quick response! I've really enjoyed using Fira Code so far with a variety of different languages.
