If you want to avoid hardcoding a class reference to Zn, you could do a simple download like this:
'http://zn.stfx.eu/zn/numbers.txt' asZnUrl retrieveContents
It avoids an entry to Undeclared or the ugly test, and it since it is
implemented as
retrieveContents
"Download and return the resource that I refer to.
This will typically return a String or a ByteArray (see
ZnClient>>#get:).
If something goes wrong, an exception will be signalled."
" 'http://zn.stfx.eu/zn/numbers.txt' asZnUrl retrieveContents. "
^ ZnClient new
beOneShot;
enforceHttpSuccess: true;
get: self
it is easy to use for simple scripting.
