But the parameters are not checked at compile-time unless you
specifically pass the pattern string as a template parameter. I
think its immutability implicitly converting it into a template
parameter is what's what he's talking about.
import std.stdio;
void main(string[] args)
{
writefln!"%s"(); // compile-time assert
writefln("%s"); // runtime exception, though everything
needed for a compile-time assert was inferable during
compilation
}
This is exactly the "use case", I thought about: How to avoid
runtime errors, if at compile time the problem might be detected.
