Is the : comment feature compliant and able to be utilized in any shell?

What is an good alternative to opening up those nice file handles that
is compliant?  It i a nifty little feature, but then again, so is
/dev/tcp/80 or whatever that crap syntax is that is utterly confusing
(there is no device like that, but bash has this "feature" to somehow
interpret this as a raw port connect)...

-v is already implied by both -e and -t ;)  And the '' argument to
echo seems unnecessary, as echo without any arguments produces the
same effect...
