Stepping through loops works now, but the counter variable does not get 
updated in the list of watches.  Wait...<tests further> that's not 
exactly true.

It doesn't get updated in this situation:

     // during first loop it's ok
     for (int i = 0; i< s.blip.length; i++) {
         s.blip[i] = i;
     }
     // but here i doesn't get updated in watch window
     for (int i = 0; i< s.blip.length; i++) {
         s.blip[i] = i*2;
     }

Declared outside of the for scope, it's ok:
     int i;
     for (i = 0; i< s.blip.length; i++) {
         s.blip[i] = i;
     }
     for (i = 0; i< s.blip.length; i++) {
         s.blip[i] = i*2;
     }



Also inout values seem to show up as void*.  Is there a way to cast a 
variable in CodeBlocks' watch list?  I tried  (int*)myptr but CB says 
"invalid expression".  I also tried cast(int*)myptr, not really 
expecting that to work, but hoping, and it didn't work either.

The program arguments just don't seem to get passed in to the debugger.

the problem is the second declaration of i within the same frame. i'll
take care of it. until then try using different counter names to work
around this.

inout's are being marked void* by DMD, a codeview issue to be added to
arrays and enums.

Ddbg's expressions don't support casts, yet. but since casts are a good
workaround to DMD's codeview issues i'll have them in the next release.
currently the expression syntax is:

Expr  = Ident
       | Ident OExpr
OExpr = . Expr
       | [ Args ] OExpr
Args  = Slice | Lit | Expr
Slice = SlArg .. SlArg
SlArg = Lit | Expr
Lit   = Int | Float | Str | Char | $

You should be able to do things like
cast(char[])(cast(mystruct*)foo.bar).strtable[key]
with it.
Any comments?

Expr                 = RefChain | Cast RefChain
RefChain             = ExprElem | ExprElem RefExpr
ExprElem             = Ident | '(' Expr ')'
RefExpr              = '.' ExprChain | '[' Args ']' RefExpr

Cast                 = 'cast' '(' Type ')'
Type                 = BasicType | BasicType QuantList
QuantList            = Quantifier | Quantifier QuanList
Quantifier   	     = '*' | '[' ']' | '[' Type ']'
BasicType            = 'void' | 'bool' | 'byte' | 'ubyte' | 'char'
                     | ... all the others ...

Args                 = Slice | Lit | Expr
Slice                = SlArg '..' SlArg
SlArg                = Lit | Expr
Lit                  = Int | Float | Str | Char | '$'
