[Swift-devel] Is the use of args within functions legal?

[Yadu Nand]

Sorry Mihael, I've pasted the error below.
Why does the error go away, when the string assignment statements are
reversed in order?

swift args_trunk.swift -foo="helloFOO"
Swift trunk swift-r7073 (swift modified locally) cog-r3787 (cog modified
locally)
RunID: 20130918-2014-t0fyb8m1
[Error] sites.xml, line 1, col 9: cvc-elt.1: Cannot find the declaration of
element 'config'.
