Every functional language I have tried has given me a compelling reason not to use it. In most cases, it was a stupid reason that had nothing to do with it being functional. Some of them force you to sort your functions by call dependence (caller must be after callee). Most of them are woefully lacking in library and toolchain support - no bindings for essential APIs, no graphical debugger, no code completion. In the end, it proved easier to add functional features to languages which already had these things and had proved themselves free of fatal flaws, than to fix the flaws and add support to the functional languages people were promoting.
