'with'ing and 'use'ing

[rh@signal.dera.gov.uk (Roger Hoyle)]

Hi,

I'm just trying to clear something up in my head.

I'm trying to interface with a lot [a *lot* :] of Ada95 code and the rest
of the code has a policy of not 'use'ing other packages, just 'with'ing
them to force the full names of types & functions etc. As a result, I'm
adopting the same attitude.

1) Is this basically a good idea? It seems sensible to me, but then I know
   little about Ada. (I'm asking about generally not 'use'ing stuff, not
   specifically my current situation)

2) One of the packages defines a sub-package called Ops, which contains
   the operators (=,/=,>=,<=) etc for some of the types in the main
   package. The only way I seem to be able to get access to these operators
   is to 'use' the package. Is this right, or am I missing somehting?

Any help gratefully received.

Thanks

rog.
