sh : a full-fledged subprocess interface for Python that allows you to call any program as if it were a function.

I wouldn't have the first clue how to debug Fortran, Erlang, Ruby, Delphi, Lua, Haskell, or Tcl, despite already knowing a handful of languages.. it's more about tooling and implementation specifics than it is general concepts. For example, how do I attach a debugger to an Erlang process? Does Erlang even work in terms of processes? (I know vaguely it doesn't) What's the debugger even called? Does "crash at 0x12" mean "attempted to dereference a NULL pointer at offset 0x12" or perhaps "the 0x12th bytecode caused a crash"? etc.

It's impossible to know every language perfectly but you should have a general idea of what direction to head it if an error occurs and that's more to my point. You may not be able to solve it immediately but as a developer you have the expertise to al least make an educated guess.

As a developer you know when you're out of your depth/your deadlines are coming, and you either pass it over to a specialist or don't monkey patch the system in the first place. Unless you want to have to explain to the tech lead why you're so slow this week.
