'' is an empty string, _and_ its length is zero (of course). So the
compiler is so intelligent as to replace length(s) = 0, or s = ''
by the same code.
Normally s = '' would be a very slow way to check for an empty
string, so
the compiler optimizes this automatically.
Thanks !
Sorry for my question not so clear :)
