For the sake of others reading this (since it is not documented elsewhere), the script that converts the `-debug.js` version into the 'raw' one strips the full line containing a `Y.log(`.  Thus, if you put the `if` along the `Y.log` the whole line will go. Unfortunately, code beautifiers and well intentioned programmers tend to *'fix'* lines such as this one and we end with conditionals with empty code blocks in the non-debug modules.
