Does remove immutability using cast to pass in a function make sense?

What is the compiler version? The following works with dmd git head:

import std.algorithm;

static immutable string[] months = ["jan", "fev" ];

void main()
{
     assert(months.canFind("jan"));
}

If it still doesn't work for you please show us a minimal program that 
demonstrates the problem.
