because 

	html anchor
		callback: [ self increase];
		with: '++' 
	html space.

is as valid Smalltalk as

	html anchor
		callback: [ self increase];
		with: '++' html space.

is. Because of the precedence of _unary_ messages over keyword messages,
this is equivalent to

	html anchor
		callback: [ self increase];
		with: ('++' html space).

hence, neither the parser nor eCompletion can know
how valid Smalltalk would be _semantically_ incorrect.
Its neither the parsers' not eCompletions fault, that
the ByteString does not understand #html ;)
