Below is a portal spell for Murk++. Programming professors talk about reaching milestones as a programmer, e.g. saving or reading from a file for the first time.

I'm asking programmers to reply a list of these kinds of achievements and estimate their difficulty so coders like me have something realistic to look forward to in addition to coming across ideas on our own.
