Primitives can be combined using:
• A parenthesized group of primitives and operators.
•
Negation (`!' or `not').
•
Concatenation (`&&' or `and').
•
Alternation (`||' or `or').
Negation has highest precedence. Alternation and concatenation have equal
precedence and associate left to right. Note that explicit and tokens, not
juxtaposition, are now required for concatenation.
If an identifier is given without a keyword, the most recent keyword is assumed.
For example:
not host vs and ace
is short for
not host vs and host ace
which should not be confused with
not (host vs or ace)
