Not really -- remember that there is "obvious" in the acronym. We should
strive to make such changes that don't violate it. For example, the "with"
statement introduced the obvious way to handle resources. The "if-else"
expression introduced the obvious way to express conditionals. Etc.
Thus spake the Lord: Thou shalt indent with four spaces. No more, no less.
Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
