> Issue 3882: Inhibit more DMD warnings

It's not a good idea to Inhibit more DMD warnings introducing spurious
variables that could generate new "variable not used" warnings:

- std.math.sin(3.0);
+ const sin3 = std.math.sin(3.0);
- std.uni.isAlpha('A');
+ const iaa = std.uni.isAlpha('A');

A better fix is to use the cast(void) everywhere.
