I've tried this, in my machine I can compile pattern matching with 1000 items but it blows up after one point and in watch compilation. It's difficult to fix this, we added a trampoline in the F# to Fable steps to avoid common failures, but because SO exceptions crash the projects I don't know exactly where it's happening :/

@alfonsogarciacaro If you try net5, stack overflow exceptions now have an actual stack trace
