[erlang-questions] Is it len/1 or length/1?

[Magnus Klaar]

Hi!

This is not the same function as the length/1 BIF exported by the erlang
module. It's just an alias for the length/1 function that must be called as
string:len(String) wheras the length/1 function can be called as either
length(String) and erlang:length(String).

It has no purpose other than to declare the intention that you want to
compute the length of a term that is a list of integers within a specific
range.
