Implement new conditional USE dep syntax:
Conditional evaluation behavior:
parent state conditional result
x x? x
-x x?
x -x?
-x -x? -x
x x= x
-x x= -x
x x!= -x
-x x!= x
Conditional syntax examples:
compact form equivalent expanded form
foo[bar?] foo bar? ( foo[bar] )
foo[-bar?] foo !bar? ( foo[-bar] )
foo[bar=] foo bar? ( foo[bar] ) !bar? ( foo[-bar] )
foo[bar!=] foo bar? ( foo[-bar] ) !bar? ( foo[bar] )
