The idiom goes like this.

/// Flag to control whether or not to keep line endings
alias KeepTerminator = Flag!"KeepTerminator";
///
string getLine(KeepTerminator KeepTerminator);

usage:

getLine(KeepTerminator.yes);
or
getLine(Yes.keepTerminator);

So named Boolean flags are a solved problem and are a good 
improvement over getLine(true) IMO.
