I think Delphi basically has the same constraints as C# so FPC is in that same category. Swift has additional constraints for compiler types but I think they can pull that off because they have protocols such as “Numeric” which can be used on integer and floating point types.

It does seem incomplete that you can’t make a generic constrained for string types for example. Why don’t more languages have that? It seems like an obvious feature which should be supported.
