I use run.dlang.io extensively to test snippets of code, and the "all dmd compilers" function is handy at times. Concretely I today wanted to confirm that std.algorithm.remove took its argument by ref since forever. A short enough example, https://run.dlang.io/is/diMup5.

import std.algorithm;
import std.stdio;

void main()
{
    int[] arr = [ 1, 2, 3, 4, 5 ];
    auto barr = arr.remove!(SwapStrategy.unstable)(2);
    if (barr != [ 1, 2, 5, 4 ]) writeln(barr);
}

But it results in a "Server error:".

Is it very unreasonable to ask that the timeout be increased? Is there some other mechanic at play?
