[swift-evolution] [Proposal] Random Unification

[Martin Waitz]

Hi Erica,

This might be useful for collections, when you want to draw several elements without drawing the same element twice.
For ranges of random numbers you usually need independent numbers and just call the generator multiple times.
Both use cases could be provided as overloads (a default argument would require that the return value has the same type, which would be unfortunate here).
