Does Functional Programming Matter to You?

I have found APL (array based) and Forth (concatenative paradigm) to both be pretty similar to FP if you squint and those are better for my needs and easier to understand without the math. The problem though is that although many open source versions of these languages exist, the best are proprietary/commercial. They're fairly cheap compared to most commercial software that I deal with, but still closed source and require a license, which is just a hassle for some uses.
