Workman-p is workman for programmers. Symbols and numbers have been switched, as well as brackets and curly braces, to make commonly used symbols in programming more accessible. The variant definition is available at https://github.com/deekayen/workman/blob/master/xorg/workman-p for your convenience. A request for inclusion has been submitted upstream as well. Meanwhile, and since this is rather non-intrusive, we could patch the layout file.
