        Alfredo, I am not a programmer and you know that, but judging for your examples it seems you (1) consider being 'modern' something good, (2) VB.Net and C# 'modern', (3) restrict yourself to the MS .Net platform.

        Well, VB.Net and C# are not that modern -- indeed, they are little more than rehashings of (Visual) BASIC and Java (C++) for the MS .Net platform.

        They are not good examples, since they are restricted to the MS .Net platform, unless you count Ximian's implementation of C# in Mono, which I don't think mature.

        Then 'modern' isn't quite useful an adjective to programming languages, since arguably some of the best languages are quite old -- Lisp anyone?

        And finally all this ignores the real issues: that languages should adapt to user-defined data types (such as those that can be defined in a true RDBMS), not the other way round; and that SQL data types are not a good example, SQL not being extensible in any sane manner.
