1255 // for example, if $x has the value timelimit, ${$x} will return
1256 // the value of $timelimit

1258 // to all alias parameters, and a number refers to that numbered

1260 // parameter is $1 and so on; as a special case, $* inserts all

1262 // pass all parameters around. All parameters starting from $n

1268 // dollar signs have no unwanted bad side effects. However, this needs to

1270 // alias foo "set x NEW; echo $x"

1274 // alias foo "set x NEW; foo2"
1275 // alias foo2 "echo $x"
1277 // Also note: lines starting with alias are exempt from cvar expansion.
1278 // If you want cvar expansion, write "alias" instead:
1281 // alias foo "echo $x"
1282 // "alias" bar "echo $x"
1285 // foo will print 2, because the variable $x will be expanded when the alias
