Trying to convert some D1 code to D2: On 2.047, I'm trying to do this:
import std.string; void foo(string str) { str = std.algorithm.map!( (char a) { return inPattern(a, [digits, letters])? a : '_'; } )(str); } And I'm getting: delegate std.algorithm.__dgliteral1 cannot access frame of function __dgliteral1 What's going on? How do I do it right? I figure I probably have some sort of problem with strings being immutable(char)[] instead of char[], but it doesn't look like that's the issue it's complaining about. Also, in this particular case, I'm not concerned about multi-unit UTF-8 characters.
