The programming-language-as-religion problem exists only in your
imagination. I fail to see Pascal as a religion. I don't know what the
pure Pascal compiler you're talking about is, but ordinary Pascal is
just another procedural systems programming language like C. It has a
bit different syntax ("begin end" vs "{}" and so on), somewhat
different rules for some default data types, but it's more or less C
wrapped in a syntactic mask.
Pick up a copy of "Pascal User Manual and Report." That's pure Pascal.
It's also quite useless. Your program has to be all in one file, for
instance. For another, writing I/O always appends a newline. Try writing
binary files with that. There was no way to get at the bit
representation of a type. Etc.
That's all gone in modern Pascal dialects. Delphi is very similar to D;
it's practically a Pascal version of D. The OOP features are the same,
except for some small differences, which make Delphi a bit more flexible
(virtual and named constructors...).
The only thing that was really lacking in Delphi are templates. But for
compensation, it had powerful RTTI. Try writing a
reflection/serialization mechanism in D that's as powerful Delphi's. I
bet you won't succeed, not even with D2. (Need to fix some compiler bugs
or deficiencies in the area of __traits first.) Even if you succeed, the
end result will be probably harder to use. (If that sounds polemic, show
me a D library that implements full serialization on
Delphi/Java/whatever level, and I'll shut up.)
