[erlang-questions] how to make the comprehension work

[Roelof Wobben]

Hello,

I try to extract the modules names from the output of code:loaded_all.

So I tried this :

-module(module).

-export([most_used_function_name/0]).

most_used_function_name() ->
    process_module_data(code:all_loaded()).

process_module_data(Loaded_modules)  ->
     Module_list = get_modules_name(Loaded_modules).

get_modules_name(Loaded_Modules_list) ->
     [ModuleList || [{ModuleList, _}] <- Loaded_Modules_List ].



but now I see a message that ModuleList is unbound.

What did I do wrong here ?
