Dynamic Addresses and PF

	if I'm using a DSL dynamic address, on an external i/f, should I be using 
the parentheses everywhere?  

ext_if2 = "tun0"
ext_gw2 = ""

	That is, on a NAT rule such as:

nat on $ext_if2 from $lan_net2 to any -> ($ext_if2)

should I write it as:

nat on ($ext_if2) from  $lan_net2 to any -> ($ext_if2)


Also, since ext_if2 is declared as "tun0" for a DSLconnection, is there a way 
to replace ext_gw2 in all my rules be something like ($ext_if2)?

That is, could I do this:

ext_gw2 = ($ext_if2) 

at the beginning of declarations to allow the ext_gw2 variable to be set to 
the dynamic IP address of the ext_if2?

Is this possible?
