{-# INLINABLE #-} loses all meaning if you apply it to every function

[ctrlcctrlv]

Every defined function is defined as {-# INLINABLE #-}.

Making a function inlinable isn't a magic word that makes it faster.

In fact, inlining can hurt performance in some cases. Especially when applied to every function.

More care should be taken to only inline functions when there's a benefit. If it was so magical, wouldn't the ghc developers inline every function by default? 🙄
