Ada may have a *reputation* of being complex and slow, but it isn't really.

IMO, Ada syntax is just as close to C and Java as it needs to be, and
also no less different than it should be.

The syntax expresses the semantics. Ada semantics is different from C
and Java and richer than both. You could perhaps use C/Java syntax to
express the subset of Ada that corresponds to C/Java, but then you would
be stuck and would have to invent new syntax to express the rest, or the
programmers would have to switch to original Ada syntax to use the more
powerful features of Ada.

How do you define a new integer type in C syntax? How do you write an
exception handler in C syntax?

So, I think it is a bad idea.

Besides, learning that similar things can be expressed in different ways
is an essential part of understanding what programming is and what
programming languages are.
