Re: make == as = ?

Dear Josh,

Thanks for you reply at length.

It helps me understand the "raw" about my suggestion.
Some short comments and joke signs:

Oracle, M$ and others spend a lot of energy so that what you write for
their tool won't be so easilly portable, thus once you've started with
them, you'll stay forever.

You're arguing that pg should help its "customers" to leave it easilly,
what is quite paradoxical! ;-)

> 3) It would, in my opinion, confuse Java and C coders

I have different classes, and not all classes would be elligible to a '=='
for '=' shorthand (well, I should write long-hand as it is longer;-).
So I partially aggree with your opinion.

For the class I have in mind, there are no corner cases, just concepts and
basic practice. They are not going to be db developers, not even computer
professionnals for most of them. I want them to remember that there is
something beside word, powerpoint and excel;-)

Sure. They should have used postgresql ;-)

"Formation" is what you need to get a job.
"Education" is what you need as a human being.

We need both...

Have a nice day,
