This will print the count of whitespace chars in a line:

What I need is the count of whitspace chars until the first
non-whitespace char is found, essentially I need a "countWhile"
template:
writeln(countWhile!isWhite(line));
Can I do this with existing templates somehow?
There is std.algorithm.countUntil, which does what's basically
the opposite. Just negate your predicate, and presto's your uncle.
