I use this idiom with tdom fairly regularly. It allows me to write
something like:

[[$node selectNodes $xpath] someMethod]

where $xpath is an xpath expression that might return 0 or 1 nodes. To
avoid having to explicitly deal with the case where no nodes would be
returned I define:

proc "" args {}
