Option to collapse iterables

I don't understand why they were collapsed in v0.1.0 but not v0.2.0. Am I missing something? I figured giving the user the option is best.

Option for explicit collapse

Fine tuning for when

• you have potential global name conflicts
• you want to unroll-then-collapse one part, and collapse-then-unroll another part of the function
• pypragma does not support something in some other part of the function
