This is not silly. This is what called a strongly typed language. D is good for people having experience with C, C++ or C# so they are fully acquainted with strong typing. BTW D and C# aren't pure because they have sytax sugar, so they're not the best choise to learn what a strong typing is.

That's kind of orthogonal. A strongly type language could very well allow the concatenation of 2 chars into a char[]. However I would expect to see it more often in weakly typed languages.

You do yourself a disservice by making assumptions on the basis of little evidence. Don't make assumptions because I choose to use Perl's slices as examples.

My more years than I care to remember history starts with assembler(various), Fortran IV, Fortran 77, BLISS; moves through REXX, APL, PL/1, PLS/86 C, C++, side trips into COBOL, Java and ADA, not necessarially in that order . On to Perl & Ruby. Daliances with Python and Rebol. And in the last 3 years, serious and studious evaluations of Haskell, OCaml, ML, Erlang, Mozart/Oz, Clean and Q. Oh. And there's a little (serious) Pascal and Prologue in there somewhere too.

As someone else pointed out, strong typing is no barrier to allowing the construction of arrays through the concatenation of elements of its base type. Lookup Curry-Howard isomorphisms.

Please don't take offence. We routinely get everything from absolute beginners that haven't a clue how things work to officialy crowned gurus. Without asking for a resume, you end up having to assuming /something/, generally on little or no evidence. People get it wrong now and again but generally stuff sort's it's self out fairly quickly.

None taken.

Just trying to throw back the red-herring of "scripters can't possibly understand type systems" before it gets mindspace. Though catching up on the "why; ?" thread(*), I see now that horse has a;ready bolted :)

Cheers, b.

Find it on the web news reader (http://www.digitalmars.com/webnews/newsgroups.php).  There are shortcuts if you are using a news reader.  In my case, using Outlook Express, I look at the properties of the message, and there is a field:

You can use this information in the web newsreader url:
