When I was learning C++ in late 90s in the university the DOS environment I was using didn't have the i18n configured properly. My teacher noticed that I was trying to use Russian transliteration for comments and she suggested to 'just use English'. That solution didn't seem obvious to me at all. Also some other day she suggested someone else to install Linux at that student's home PC. I followed that advice too and learned a good bunch much of my English by reading man pages.
