Well, we do already have:
print $foo.as('%03d'), $bar.as('%15s')
which works on interpolated values as well. It als puts the variable
name out front, since the name is more important than the pattern in
most cases.

I don't see that this buys us anything over just shortening "sprintf"
to something shorter, like:
print as '%03d %15s', $foo, $bar;
And your argument list falls out naturally from making "as" a listop.
Plus it naturally lets you say other "as-ly" things:
print as MyBigInt, $foo, $bar;
: If this feels weird, just think of s///e,
: where the RHS is also not a string.
Um, actually we did away with /e in Perl 6...
