Thank you very much. I think you have exposed me to  a number of 
new concepts that I will go through and annotate the code with.  
I read all input from file as follows.

string text = cast(string)std.file.read(inputfile);
foreach(record;FastQRecord.parse(text)){
    writeln(record);
}

</naivequestion>Does this mean that text is allocated to memory? 
and is there a better way to read and process the inputfile?
