I'd like to use std.math.abs on a BigInt too:

import std.bigint, std.math;
void main() {
    auto r = abs(BigInt(-1000));
}


But dmd 2.054 gives:

...\src\phobos\std\math.d(251): Error: pure function 'abs' cannot call impure
function 'opCmp'
...\src\phobos\std\math.d(251): Error: safe function 'abs' cannot call system
function 'opCmp'

Line 251 of math.d is:

return x>=0 ? x : -x;
