28860	Reduce calls to len()	Дилян Палаузов	nobody	"{{{if len(x)}}} is the same as {{{if x}}} except when {{{len()}}} is supposed to throw exception when {{{x}}} is not iterable.

{{{len(x)}}} can return either zero or a positive integer, hence {{{if len(x) < 1}}} is the same as {{{if len(x) == 0}}} <=> {{{if not x}}}.
