Most(ly dead) Influential Programming Languages
There are a few things present in COBOL that I would like to see lifted into more modern languages. One is the use of the full stop as an expression terminator, as in English, instead of the semicolon. Another is the whole "picture" mechanism for number formats.<p>More languages should also steal Verilog's use of _ as an optional digit separator. It's just arrived in C# 7.
