Summary: Stride in foreach ranges Product: D Version: future Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2010-04-21 14:09:48 PDT --- In D2 the range syntax of foreach is useful because it helps state the iteration variable one time only instead of tree, it's cleaner and less bug-prone than the normal for syntax, and it's useful in many situations because many for loops are just over a numeric range (so the normal for syntax can be left for more complex situations). But beside natural series, for loops over arithmetic ranges too are common. Currently in D2 this requires a normal for syntax: for (int i = 0; i < 100; i += 2) {} My experience with Python tells me that an optional stride can be useful here. This is a possible syntax (the colon is useful to visually tell apart the third value): foreach (i; 0 .. 100 : 2) {} (To keep things simpler, it can even be acceptable for the stride value to be a value known at compile-time).
