You mean you want to accept |a,b;c,d| as a*d-bc ?
This would be confusing with the other uses of |.

The major issue is that there are no different left | and right |
characters to bracket the matrix entries.

Maybe you can change src/language/parse.y (and compile.c) to
handle this but I would not advise it.
