matlab? custom function was (or still is?) a one-function-one-file. i had bunch of function-files in a project directory. my mind was literally scattered. then i moved on to languages that allow binding function to variable. i had much less files. simpler. FP with anonymous function further frees my mind from naming variables so i have zero chance of mistyped function names. easier maintenance? sure those didn't stop me from getting work done; however, i prefer to not waste time on weaker programming languages, although coding on those languages did broaden my mind (yeah, now i know they suck)
