Not so far as I recall (but I probably haven't used LST since '88) and if it was that way it would have been incorrect. “Isn’t this the way Tim Budd’s Little Smalltalk always interpreted the plain cascade operator?”

Since Smalltalk already uses left arrow (←) for assignment it should not be too surprising to see right arrow (→) used for message chains. Since most keyboards do not make it easy to insert arrow characters, Smalltalk allows := for left arrow; similarly, =: could be used for message chains.
