Confusing Date parsing

'9.7.2015' asDate  returns the 7th of September, I would have expected 9th of July
because in Date readFrom: comment it is stated:

  readFrom: aStream
     "Read a Date from the stream in any of the forms:
      <day> <month> <year> (15 April 1982; 15-APR-82; 15.4.82; 15APR82)  
      <month> <day> <year> (April 15, 1982; 4/15/82)
      <year>-<month>-<day> (1982-04-15) (ISO8601)"

According to this the order day, month, year with a $. as separator should be valid.

When I try '15.4.82' asDate als does not work, it gives an error that the month is exceeded with 15...

Looks like this is not correctly implemented/backed up by tests. Or the comment is just wrong.
Should I open an issue?

Thanks
T.

Also

  Date readFrom: '9.7.2015' readStream pattern: 'ddmmyyyy'.

works, but

  Date readFrom: '23.7.2015' readStream pattern: 'ddmmyyyy'.
 
throws an error. I'm confused...

Hmm, this particular case (any case involving two numbers <= 12) is non-deterministic when no expected pattern is given.

Smalltalk was written in the US, so they chose their date format as default.

So by default it goes for the American format, month first. From that perspective it is correct.

I did not look at the implementation, but I think there is no real universal solution.
