It's also built into all modern shells (e.g., SV Bourne, Korn).
Not only that, but most experienced users put the current directory
LAST in their $PATH to avoid unpleasant surprises while browsing, or
leave it out of the $PATH altogether (then type "./myprog" to run
"myprog" in the current directory), so that /bin/test would still get
executed instead of the local directory's "test".
