digitalmars.D - Removing the "int foo[];" syntax

It complicates the grammar and doesn't fit with D's style of 
declaraing variables. (type then identifier) I realize that it 
was left in to make C programmers happy, but it doesn't even work 
like it does in C:

int a[10];
int b[10], b[10];
int[10] c, d;
int e[string];
int f[string], g[string];

test.d(2): Error: multiple declarations must have the same type, 
not int[10] and int[10]
test.d(5): Error: multiple declarations must have the same type, 
not int[string] and int[string]

I would say no if it was removed.

I suggested something more moderate: to just disallow mixing C 
and D syntax in the same declaration:
http://d.puremagic.com/issues/show_bug.cgi?id=5807



 I realize that it was left in to make C programmers happy,


For that I suggested a -cstyle switch, to be used only 
temporarily to port C code to D:

I remember being mentioned by someone that it is more about 
simplifying porting of C headers to D than actually making C 
programmers happy.

Array are value type in D so I'm not sure this really helps.

I think that deprecating the C-style syntax has been considered in the past, 
but I don't know what Andrei or Walter's stance on it is. I don't think that 
it adds much value though beyond making it slightly easier to port code from C 
to D, and I'm all for removing it. Most D programmers are probably using the D 
syntax anyway.
