5 List Handling 5.1 Creating a List. Lists can only be built starting from the end and attaching list elements at the beginning. If you use the "++" operator as follows, a new list is created that is a copy of the elements in List1, followed by List2:

Using lists:foreach is a better solution - this is much faster than the list comprehension, and no need to nest the function.

It converts a process id to a list. Syntax Pid_to_list(processid) Parameters If your F outputs something like a list of 255 integers, then running it enough times is slower inside a list comprehension than calling G(). Perhaps this is due to the overhead of building up the list. Using lists:foreach is a better solution - this is much faster than the list comprehension, and no need to nest the function.

Lists comprehensions still have a reputation for being slow. They used to be implemented using funs, which used to be slow. In recent Erlang/OTP releases (including R12B), a list comprehension By convention, most Built-In Functions (BIFs) are included in this module. Some of the BIFs are viewed more or less as part of the Erlang programming language and are auto-imported.
