Yes, that is an incorrect way to use the ?: operator -- the operataor is
handed an expression that yields a boolean value, and it returns a value
based on what that boolean value is:
Here is a one liner that accomplishes what you want:
$ perl -e '$ans = (-d "/usr/bin") ? "yes\n" : "no\n"; print $ans'
yes
