What about the empty() function, for clarity and speed?
empty({expr}) *empty()*
Return the Number 1 if {expr} is empty, zero otherwise.
A |List| or |Dictionary| is empty when it does not have any
items. A Number is empty when its value is zero.
For a long |List| this is much faster than comparing the
length with zero.
