I knew a physicist who only programmed C++ in notepad. He was having some problem with some multiple-body simulation he was working on, and I took one look at his code and told him to paste it into Gedit or Notepad++ or something (since he was a die-hard anti-Emacs/Vim zealot.) He refused, couldn't figure it out, did an "exact transliteration" of his code into Python and suddenly it worked.
