I think this is an issue with Phobos, not the compiler.

The error is now slightly better (first two shown):

Error: mutable method std.random.LinearCongruentialEngine!(uint, 48271, 0,
2147483647).LinearCongruentialEngine.front is not callable using a const object
Error: mutable method std.random.LinearCongruentialEngine!(uint, 48271, 0,
2147483647).LinearCongruentialEngine.popFront is not callable using a const
object

uniform() should probably reject a const random number generator. And this is
probably true for all range-taking functions. If you can't call popFront then
you can't do much with the range AFAICT. Not even .save helps in this case.
