The namespace issue alluded to doesn't exist when using the very
similar approach suggested earlier in this thread by Andrew Durdin --
shown again below in a [very] contrived example illustrating access to
the local namespace:

	greeting = "Hello there, "
	x = 2

	exec {
	    1: """greeting += 'Tom'""",
	    2: """greeting += 'Dick'""",
	    3: """greeting += 'Harry'""",
	}.get(x, """greeting += 'Unknown'""")
	
	print greeting
