I'd call this a documentation issue. It's obvious you're passing true to
the function. Of course, if you want to mitigate this somewhat,
something like this could work:
struct FuncFlag(alias func)
{
// See code from above, but use typeof(&func).stringof to get
// a list of parameter names and make sure the passed name is valid
// of course, you can't check position, but the only way to get
// around that is named parameters or some sort of compiler support
}
alias FuncFlag!generatePdf PdfFlag;
// This now fails to compile
generatePdf("doc.pdf", PdfFlag.nook);
