  If it was, then it could be used anywhere where a string is expected.
It can't.
  For example the #debug command takes as parameter a string. A string
can be a string literal, a string identifier or a string function. Since
strlen() is not a string function (but a float function) it can't be given
to #debug.

  Its location would not change the fact that it's a float function
(there's no reason why there could not be float functions in a string
class).
