Maybe not. ;-) I'm with you. In my 12 years of perl programming, I've never needed anything that goes beyond the scope of that old friend from my preceding 10 years with C: (s)printf.

Maybe some of my code would be considered by some as "too complicated" or even "suboptimal" as a result, but it's really just a matter of what you happen to be comfortable with.

(And Perl is that rarety among programming languages, where the choice of solution can be a matter of one's own comfort level, rather than being dictated by syntactic constraints or a limited library of available support functions.)
