[swift-evolution] Feature proposal: Range operator with step

[Ted F.A. van Gaalen]

Hello Milos,
Good question
was thinking about this too.
that would imply the ‘by”value should/must always be an absolute value?
however (if it is a var) it cannot be guaranteed to be + or - 
that’s why I thought to leave it as is.
?
