Aye

It always did. Long, long before the first release in January :)

Anyway, FWIW, here's the distinction between those two:

Stdout() is a shortcut, where you just want to dump some output to the 
console. Unlike Stdout.format() it does not support a format-string. 
Instead, it just emits a comma-separated list of the arguments, because 
that's how you type them:

# Stdout (10, "foo", 20) => "10, foo, 20"

It does this via a little lookup table, and there's a limited number of 
patterns supplied.

Stdout.format() is different only in that 'you' supply the formatting 
arrangement.

Ach! Do I detect the scent of a new Ticket? :D
