This is ambiguous because there are two ways to interpret 
this. Take the following example.

z = (function(...) print(...); return "Bar"; end)
("Foo"):sub(1,1)

There are two interpretations to this:

1) Store the newly created function, which calls print and 
returns "Bar" into the variable z, then call string.sub on 
"Foo" and discard the result

2) Create a temporary function which prints out the parameters 
and returns "Bar", pass in "Foo" to that function, then 
execute string.sub on "Bar" (returning "B" to store into 
variable z)

Use a semicolon to disambiguate this problem.
