I get the following error when using tolower():

/path/to/src/phobos/std/string.d(775): Error: shadowing declaration std.string.tolower!(immutable(dchar[])).tolower.c is deprecated

tolower appears to be broken with dmd 2.048. Looking at the code, it looks like essentially what's happening in that there's a foreach within a foreach, and they both declare dchar c for the loop variable. Looking at the unit tests, they should have caught this, but either they didn't or the phobos in dmd 2.048 was released without passing all of its unit tests.

In any case, it should be a trivial fix, but it means that if I want to use tolower, I have to patch it on my box, which obviously shouldn't be necessary. At least it should be a quick and obvious fix for anyone with commit prvileges.
