Sure, but I don't think I want to pay the cost of the exec statement.
if/else would probably be quicker.

 -- shown again below in a [very] contrived example

    Martin>     greeting = "Hello there, "
    Martin>     x = 2

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