[erlang-questions] What I dislike about Erlang

[Max Lapshin]

Guys. It is nice in theory, but I have other practice.

For example, there is such a protocol, like MPEG-TS (in fact, problem
is deeper, it is a whole set of protocols).
There is no single program, that implements it for 100%. Every program
lacks something.
Without source code it is impossible to find out, what is the problem.

So I consider, that "black-box" approach doesn't work, because every
code has bugs. If you can't modify this code, don't use it in your
program at all.
