The Smalltalk grammar does not seem ambiguous. Your example

	receiver kw1: arg1 kw2: arg2
	nextmessage: arg

would send a message with selector kw1:kw2:nextmessage: to receiver.
If you wanted nextmessage: to be sent to the result of kw1:kw2: you
could use parentheses:

	(receiver kw1: arg1 kw2: arg2)
	nextmessage: arg

Alternatively, both messages may be cascaded to the same receiver
using a semicolon:

	receiver kw1: arg1 kw2: arg2;
	nextmessage: arg

Despite all the discussion about indenting code, compilers ignore
information contained in the format of a program.
