Let me guess, you were downcasting everything to std_logic_vector? If you have to cast things all the time in VHDL you're not using it correctly. But please enjoy (System)Verilog with it's random often undefined coercion, implicit wire declarations, non-deterministic simulation and lack of any meaningful compile-time checks. Honestly, as a huge Haskell fan, I can't believe you're a Haskell fan.
