The "creative" part is all decisions to be made before coding: architecture, design, modularization, algorithms, APIs, etc. If I am in charge of those decisions, I can use Perl to build a prototype, to validate the solution I am creating. But if I don't decide anything, my job is to code whatever. No chance for me to be creative. Most quirks of Perl are there to make the construction of prototypes easier and faster.
