1089 // alias foo "set x NEW; foo2"
1090 // alias foo2 "echo $x"
1092 // Also note: lines starting with alias are exempt from cvar expansion.
1093 // If you want cvar expansion, write "alias" instead:
1096 // alias foo "echo $x"
1097 // "alias" bar "echo $x"
1100 // foo will print 2, because the variable $x will be expanded when the alias
1101 // gets expanded. bar will print 1, because the variable $x was expanded
1102 // at definition time. foo can be equivalently defined as
1104 // "alias" foo "echo $$x"
