on versions. Meaning:  should the following functions return a version
   

data
 

type :
   assembly::get-version(string)
   file::get-file-version(string)
   file::get-product-version(string)
and we could then have the following functions in the version namespace :
   version::get-major(version)
   version::get-minor(version)
   version::get-build(version)
   version::get-revision(version)
   version::to-string(version)
   version::parse(string) or version::from-string(string)
and support the same operators as supported by the System.Version.
   

Imagine this extension to NAnt function calls:
assembly::get-version('aaaa.dll')::major
assembly::get-version('aaaa.dll')::minor
assembly::get-version('aaaa.dll')::build
assembly::get-version('aaaa.dll')::revision
('.' as a member access operator cannot be used because it can be a part of
a valid identifier)
Same thing would work for functions that return datetime, timespan and other
structures.
datetime::now()::seconds
timespan::whatever()::totalseconds
In the future when we support typed properties, you'd be allowed to do it
even on properties:
<property name="zzz" type="datetime" value="${datetime::now()}" />
<echo message="${zzz::seconds}" />
What do you think?
 

Way too many colons for my liking. I understand why . isn't an option 
but :: for method reference looks pretty ugly.
I'm not sure we need NAnts expression language to become a fully fledged 
object oriented language.
