Yes, they are.
What you have described is the behaviour of the Bourne shell when it parses a line and searches for a command. If it sees a path component in a command name, it searches from either the filesystem root or the current directory. Otherwise, it uses $PATH, which does not usually contain ".", for security reasons.
Actually, this is done by certain variants of the exec*() family of system/library calls.
As you can now imagine, this has no relation to how a Haskell program should be manipulating paths.
What, Haskell programs won't ever be manipulating paths of executables it will be calling? -- Aaron Denney -><-
