[swift-evolution] [Discussion] Design guideline rule for `:`

[Vladimir.S]

Good question. I also asked myself if there is such guideline.
I thought we have some kind of guideline, as parameters in methods/funcs in 
Swift has `func foo(param: Type)` format, not 'func foo(param : Type)'. So 
for myself I decided that I should follow this syntax anywhere I need to 
place `:`.
