Jeeze, perhaps you don't like the word perhaps.

There is no absolute defect here.

There are unnecessary pushes to stack that are
unwound by the compiler.

Stylistically, format/argument mismatches can
cause errors.  It's
generally bad form and error
prone to use non constant strings as
formats.

Note it's not signed and is a simple suggestion.
If you don't like it, don't do anything with it.
