I'm always listening :) Thanks.

There are many tradeoffs, really. If you can do function calls early
on a LHS and prevent further matching, then using them will help
performance, not hurt. Similarly, it's better to do complicated tests
on the LHS than it is to match more generally and then use an if-then
on the RHS to sort things out. But all things being equal, if you can
easily write simple procedural code to make a decision, it often is
better to do that than to do it via pattern matching.
