An unspoken coding convention.

Function foo' would be read "foo-prime". E.g.of usage: haskell-prime is the
next standard of haskell, which became moot because you need good vibes for
diverse peoples to collaborate on such an undertaking, including supporting
it by writing more than one implementation.

Strictly syntax, the compiler doesn't treat it differently from any other
name label.

So yes, you could have foo-double-prime and so forth.
