If you really want to compare Ada with functional languages, you
should try Erlang. The promise of functional languages are in non-
mutable variables and functions with no side effects which qualifies a
language as being a "pure functional" language. Erlang is almost a
subset of Haskell, the only difference is that its dynamically typed.
It relies on pattern matching with guards much as Haskell does. But
what sets Erlang apart from Haskell is that threading is built into
the language so that it has practical value in dealing with the
outside world. Whereas with Haskell needing modads to communicate with
the outside world, program state is saved in threads with Erlang. I
think if you experiment with threading with Erlang and then with Ada
you will find that the tasks in Erlang will provide more practical
concurrency. Im not saying one is better than the other, I leave that
up to you to decide.
