[squeak-dev] Timespan>>datesDo: - is this a bug?

So, this code:
   Date today asMonth datesDo: [:date| Transcript cr; show: date yyyymmdd]
prints out each day in the month.  That is what I'd expect.

This code:
  mth := Date today asMonth.
  (mth start asDate to: mth end asDate) datesDo: [:date| Transcript cr;
show: date yyyymmdd]
does not print the last date.

This has bitten me.  If I add a nanosecond onto the end date (mth end
asDate + 1) it does include the last date - but that is ugly.  And
dangerous if I have other code that carefully picks the following date
start to work around this oddity.
