Hi Jarek,
I agree that this looks more readable, but I'm not sure its good to add
another way to create datetime or timespan instances. We'll need to retain
the convert::to-datetime/timespan anyway ...
We should also stick to using the .NET framework conversion routines to
handle conversion to and from datetime/timespan. Maybe one day we'll allow
users to define the culture in which they want to run NAnt ...
Again, I agree that this is not very readably, but I think this is a problem
with the expression support as such ...
