It's totally ambiguous.
Suggestion: do not mail syntax ideas without working through (pencil and paper,
Jison/Bison/Antlr/something, or better) the grammar.
More specific suggestion: don't bikeshed function syntax without a new prefix
character or a convincing top-down parsing story. If you don't know what
top-down vs. bottom-up means, find out first.
