Something similar for human languages:
"The principle of least effort is another possible explanation: Zipf himself proposed that neither speakers nor hearers using a given language want to work any harder than necessary to reach understanding, and the process that results in approximately equal distribution of effort leads to the observed Zipf distribution.[5][31]" -- From: https://en.wikipedia.org/wiki/Zipf%27s_law
"Explicit syntax" would initially be less cognitive effort. Soon that effort would be gone and "terse notation" would lead to lesser typing effort.
