it is not inconsistent, last option is incorrect and should not be used. 

what you do there is to declare: directory ‘tmp', file ‘a/b/c.txt’
is casual that it coincides with a real path, but it is not semantically 
correct, that’s why x ~= z  

there was an issue around to explicitly forbid to declare a file like that, but 
I was (and still am) not sure it should be forbidden… is not the spirit of 
smalltalk… you know, great power/great responsibility thing :)

but it causes confusions (as this one), so at least needs to be correctly 
explained somewhere :)

cheers,
Esteban
