The candidate was writing an accounting program in COBOL and he wrote "ADD 2 TO SUM.". None of the handful of languages I kind of know support that syntax. It turns out that COBOL actually supports this nonsense. I explained to the candidate that when he is writing valid COBOL syntax, it is confusing to people who don't know COBOL and he agreed.

This is a fail for the interviewer, not the interviewee, nor for Python.
