import std.range;
import std.stdio;

void main()
{
   auto r1 = iota(0.0, 4.0, 0.03);  // ok
   auto r2 = iota(0.0, 3.0, 0.03);  //
core.exception.AssertError@std.range(4001): Assertion failure
}

I want a range in steps of 0.03, beginning at 0.0 and ending at the
closest point to 3.0.

Line 4001 is:
assert(start + count * step >= end);

There's no documentation, and no custom assert message, so I don't know what
was the intention of the author.

It doesn't help that this fails in debug mode but works fine in release mode.
