Description Ali Cehreli 2015-10-24 22:16:50 UTC 
void main() {
    double.min;
}

Error: use .min_normal property instead of .min

I like the warning but it is misleading. When a person (especially a beginner) writes double.min, they mean "the minimum value" but the warning tells them to use something else: double.min_normal.

I recommend that the message be changed to something like

Error: .min is deprecated for floating point types. Do you mean -double.max or double.min_normal?

This currently produces the message:

  test.d(3): Error: no property `min` for type `double`

Not sure when or why it was changed.
