It reminds me a bit of Delphi 1. Borland has always provided the means to access the Windows API in Delphi, and people swore you
couldn't live without it in D1. Well, maybe, but since D2 went 32-bit and added a bunch of other stuff, the entire design has evolved
to the point where it really isn't necessary for most typical needs to ever step outside the VCL. But, if you do, it's a very _short_
step. <g> The advantage today is that the CLX architecture is based on a fifth-generation VCL model -- IOW, it's had time to mature
nicely. Whereas D1 was really raw and the only thing you had to compare it with was VB/DOS, D5/D6/Kylix compare very well against any
other similar tool around.
Once I grokked object-oriented programming and C++, I could never go back to plain c programming. If you haven't gone through that
transition, you really can't relate. As a result, I find the non-OO nature of VB as cumbersome as in c. Delphi's model is pure OO,
PLUS the way it integrates things into the IDE makes it highly productive.
Something was posted yesterday that indicates Borland might be working on something that, for lack of a better name, might be called
"D-flat" (Db ?) that will support both .Net's C# as well as Delphi/Kylix environments. Borland is really pushing hard at neutralizing
the bias MS is generating around their .Net initiatives.
