Re: C# is not Dylan (was: Re: C# : The new language from M$)
Argh. Syntax semantics? Is that a valid phrase?
I meant that within the language syntax you have markers for beginning and
ending blocks, blocks are scopes, and lines generally end with an end of
line marker. I know this sounds trivial, but the fuss people make over
syntax tends to obscure this.
So, despite having each others' programmers reaching for their Red Books,
these are equivalent:
// C
void klin()
{
if( true )
{
exit( 0 );
}
}
// Dylan
define method blim()
if( #t )
exit( 0 );
end if;
end method blim;
Whilst the Dylan takes more typing (in this hyper-correct form), you get
better documented code and you don't have to start blocks twice as you do in
curly-bracket langauges.
You are right that the examples were entirely syntax, this was what I meant.
