Right now, there is:
TxBasicSpan>>#isAtEnd ^ false
and
TxEndSpan>>#isAtEnd ^ true
However, there are cases were a list of spans has no end marker e.g. the
argument to #insert:
I'm thinking of changing to: TxBasicSpan>>#isAtEnd ^ self next == self.
This will allow changing e.g. the following slightly opaque loop condition:
[ span next == span ] whileFalse: [ span := span next ].
to:
[ span isAtEnd ] whileFalse: [ span := span next ].
All tests pass with this change, but I'm still very much beginning learning
Tx, so I wanted to run it by everyone to see if I'm missing something...
