Yeah. (Anyone know why Ada stops at base 16?)

I like this.

Library problem. It should be kept in mind as a syntax issue.

I'm not sure what you're looking for.

  [ struct layout ]

Must this be forced upon the compiler? Quality-of-implementation issues
are important but I can't imagine a portable program taking advantage of
this.

Yeah. JHA suggested ``inherit''---makes perfect sense to me.

  [ integral[1..29] ]

This seems reasonable.

  [ % ]

Would someone please show me an example of a real program that uses C's
% in a context where not knowing the sign would be okay? Until that
example shows up, this argument is purely facetious.

It's fine to have two portable operators with different results, like
Ada's rem and mod.

Do you mean an actual array of bits? How would you integrate this with
the normal meaning of arrays?

Wait a minute! C's weak typing has nothing to do with the overloading of
its conversion functions. Even Ada, with the strongest typing around,
has overloaded conversions. Merely introducing the above change wouldn't
do anything to C's type checking.
