This module allows for evaluation of local functions in any module as long as there is 'debug_info' present in the corresponding beam file.

For those times when you really want to test a local function from the shell, and cannot recompile the module.

Example:

Code:

Eshell V5.5.4.3  (abort with ^G)
1> lfun:eval(lists,sublist_2, [[1,2,3,4,5],2]).
[1,2]
2> erlang:function_exported(lists,sublist_2,2).
false
3> Abst = lfun:load_abstract(lists).
{lfun,
    lists,
    {dict,
     ...}}
4> lfun:eval(lists,sublist_2, [[1,2,3,4,5],2], Abst).
[1,2]
[/code]
