Hi Ian!
Please, don't do this kind of tricks. It is like shooting yourself in the
foot. Functions (by definition) should be side-effect-free and nobody is
advised to do otherwise.
I was just going to propose a patch that would prevent ANY writes to
property dictionary during property evaluation, just to prevent this kind of
abuse.
BTW. I think that because version info is a complex structure, a task would
be more conventient here:
<get-assembly-version assembly="aaa.dll" propertyprefix="xxx" />
This would set the following properties:
xxx.minorversion
xxx.majorversion
xxx.buildversion
xxx.privateversion
xxx.author
...
xxx.copyright
