+ // - ${var !} fails expansion and executes nothing if
+ // $var does not exist
+ // - prefix the cvar name with a dollar sign to do indirection;

+ // pass all parameters around. All parameters starting from $n

+ // Also note: lines starting with alias are exempt from cvar expansion.

+ //
+ // set x 1
+ // alias foo "echo $x"
+ // "alias" bar "echo $x"
+ // set x 2
+ //
+ // foo will print 2, because the variable $x will be expanded when the alias
