Admittedly I only programmed in Ada for a few months, but I found it to be an unbearably tedious language. The verbosity is monstrous--- the type system is inexpressive; it feels primitive. Nothing is inferred, everything is repeated. Ugh, I would rather code exclusively in C++ templates than touch Ada again.



I will freely admit that Ada is not appropriate for all uses. But for the sort of thing you'd want to use Ada for (life critical systems, critical infrastructure, control systems, etc) The explicit type system, explicit declaration, statically typed system is ideal. I particularly like the ability to declare down to the bit level how my data is stored. Very useful for working with low level hardware.

Take a look again, with an eye towards large scale long lived critical systems. You'll find that explicitness a feature, as is the very strict static typing.

Oh, and they got pointers right the first time.

EDIT: Forgot to mention the coolness of the type system - you can declare ranges and other type information and the compiler will hold that requirement strictly. for example type direction is range 0..359; Declares the obvious, but now you can have the compiler error if you assign a direction type with a value that might be outside that range. Even if you don't set that option you can always use the foo'valid attribute to check that foo is within bounds. This is used to check for stray cosmic radiation (seriously!).

Yes it seems like overkill. But when you come back to 20 year old code that's still running you'll smile.


I would also add that Ada compilers do generate some surprisingly efficient executables. This helps quite a lot in the embeded space.
