digitalmars.D.learn - Sort using Uniform call syntax

I have a small problem with using UCS when sorting arrays. This 
pops a warning telling me to use the algorithm sort instead of 
the property sort. Which I understand why it works that way. 
However that means I can not have syntactic sugar. So is there 
any way around this or do I just have to live with it?

Two options: a) Use parentheses after sort: arr.sort() b) Import sort() under a different name: import std.algorithm: algsort = sort; arr.algsort Ali

      arr.sort()

 b) Import sort() under a different name:

 import std.algorithm: algsort = sort;

      arr.algsort
Yep. The sort property on arrays will likely go away eventually, but until it does, those are your options. But at least now it warns you. Previously, it just silently used the sort property, which does the wrong thing for arrays of char or wchar. - Jonathan M Davis

Do you mean property sort would sort individual chars? However, the following program indicates that it may have been fixed (i.e. made Unicode-aware): import std.stdio; void main() { auto arr = "√ß√∂√ľabc".dup; arr.sort; // (Not correct for a particular writing system but // that's beyond the point. It's still a correct string.) assert(arr == "abc√ß√∂√ľ"); foreach (c; arr) { writefln("%02x", c); } } Prints: 61 62 63 c3 <- Out of order a7 <- etc. c3 b6 c3 bc Perhaps, this was an independent change? More likely I've misunderstood you. :) Ali

It was my understanding that the built-in sort did indeed sort individual chars, so if that's not currently the case, I expect that someone fixed it at some point. Still, it should be removed from the language at some point. - Jonathan M Davis
