Re^2: Get the length of a list.

in reply to Re: Get the length of a list.
in thread Get the length of a list.

Lists are not arrays!

see FAQ#What is the difference between a list and an array?

for instance the easiest way to know how many values a function or a grep returned is using a goatse:

 
  DB<101> sub tst {a..z}

  DB<102> $length =()= tst()
 => 26

  DB<107>  grep { $_ % 2 } 1..10
 => (1, 3, 5, 7, 9)

  DB<108> $n =()= grep { $_ % 2 } 1..10
 => 5
