Tuple fields/types

[Jordan Wilson via Digitalmars-d-learn]

Hello,

For tuples, does the fieldNames property have a 1-1 
correspondence with the Types property?

It appears that way in my testing:

alias MyData = Tuple!(string,"a",int,"b");
foreach (i, type; MyData.Types){
    writeln (MyData.fieldNames[i]," ",type.stringof);
    // a string
    // b int
}

But I can't figure out for sure from the documentation:

alias fieldNames = staticMap!(extractName, fieldSpecs);
alias Types = staticMap!(extractType, fieldSpecs);

Thanks,

Jordan
