           Summary: std.algorithm functions conflict with std.string
                    fucntions

Given these two minimal programs:

import std.string;
void main()
{
    string str = "abc";
    int i = str.count("ab");

}


and:


import std.string;
import std.algorithm;
void main()
{
    string str = "abc";
    int i = str.count("ab");

}


The only difference is line 2, where I import std.algorithm.
The first program compiles fine, but the second program does not compile,
spitting out the error message:



bash-3.2$ dmd -ofdummy dummy.d
/u/sah2659/dmd2/linux/bin/../../src/phobos/std/functional.d(176): Error: static
assert  "Bad binary function q{a == b}. You need to use a valid D expression
using symbols a of type dchar and b of type string."
/u/sah2659/dmd2/linux/bin/../../src/phobos/std/functional.d(179):       
instantiated from here: Body!(dchar,string)
/u/sah2659/dmd2/linux/bin/../../src/phobos/std/algorithm.d(3410):       
instantiated from here: result!(dchar,string)
dummy.d(7):        instantiated from here: count!("a == b",string,string)



A little more investigating reveals that std.algorithm.indexOf and
std.string.indexOf also conflict.
