It could mean a lot of things. Assigning too much meaning to passing statements is a bad idea. However, I can't resist speculating:
Don't tell me to use strict and warnings.
Don't tell me to figure out a new module.
If we need a new module, you install it and take care of all the details.
Don't tell me to write a simple test program. I want to spend all my time working on broken code.
Don't be pedantic. This is not a teachable moment.
You can work on it, but only if you just fix it and then go away quietly.
It should work perfectly the first time! - toma
