But way less verifiable with a quick look. Keystrokes are much less important than understanding. The long winded suggestion I made is easy to understand even if you don't speak Perl and is easy to check. Anything that breaks the obvious one to one visual mapping between the letter and its repeat count is a step backwards for maintainability and easy understanding.

Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond
