hi why whith this code : http://dpaste.dzfl.pl/474dd9f6

i get these errors:
parser/fasta.d(171): Error: cannot infer argument types
parser/fasta.d(176): Error: undefined identifier index, did you 
mean template indexed(Source,Indices)?
parser/fasta.d(177): Error: undefined identifier index, did you 
mean template indexed(Source,Indices)?

mean template indexed(Source,Indices)?
parser/fasta.d(180): Error: undefined identifier index, did you 
mean template indexed(Source,Indices)?
parser/fasta.d(183): Error: undefined identifier 'header'


what is wrong at line 171 ? i am explicit i said i want a counter 
iterator and a Fasta struct!

I try to use :
      property
     Tuple!(size_t, Fastq) front(){
         Tuple!(size_t, Fastq) result;
         result[0] = _i;
         result[1] = _extract( _sections[0] );
         _i++;
         return result;
     }


but it seem is not aggregate by the foreach loop :-(

fastqFile.byFastq() return a Tuple!(ulong,Fastq) in this case 
foreach fail to aggregate correctly

Generally if you want to help who gives help you have to show the 
full code (or its compilable reduction) and copy&paste the error 
you get...

Try to minimize the code that produces this problem, so if it's a 
real problem it becomes fodder for Bugzilla.
