No, that case would not cause the inclusion of an implicit semicolon.
I certainly should have discussed such cases. But I have covered them
in the blanket statement "C) and other cases that would also cause the
parsing to return an error" because I am confident that the parser can
handle them.
What I said:
My proposition could then be expressed informally:
Newline is interpred as statement terminator when it makes sense.
It does not when :
A) in the middle of an expression when an operand is expected
B) within a parenthesised expression
C) and other cases that would also cause the parsing to return an error

I am certainly confident that in perl6, everyone will be able to bake
his own grammar. I am also confident that the grammar will be good
enough that we will not have to do it in the general case
