There is one problem with using no keyword: You cannot use arbitrary expressions
in the new statement. Consider:

resource = opening("file.txt")
block resource:
    (...)

resource = opening("file.txt")
resource:
    (...)

The latter would have to be forbidden.

(Seeing these examples, I somehow strongly dislike "block";
"with" or "using" seem really better)
