I agree that such mathematical syntaxes are more commonly known 
than the ... syntax that is used in Perl and I think Ruby and few 
other languages.

In other nations mathematicians use [x, y[ to represent open or 
close intervals (that syntax is used in std.random too).

So maybe instead of (in interval x ... y) it's better to use (in 
interval [x, y]) and hope people will understand this doesn't 
follow the normal D/Python usage of closed-on-the-right intervals.

I have added a note in the ER:
