Ryan McConnell 2d30ebaea9 fix 25778; concept coerces incompatible types (#25781) 
I don't like it, but seems like this is correct. Concept type classes
have to behave like other "named" type classes and participate in "bind
once" mechanics or require some weird semantics. As a side note I'm
pretty sure the `tuple` example in the manual explaining this is either
wrong now or has regressed, but I don't think it matters because I doubt
anyone thinks about this feature much.
#25778

  • Note that this code has been translated from a bootstrapping version written in Pascal.
  • So the code is not a poster child of good Nim code.
