bash {2..4} Variable Indirection

Bash v4 uses new quoting syntax, $"...", to do locale-specific string translation. Some scripts of mine that used bash-1.14 style variable indrection need to change. I was doing something like this to get the value of a variable whose name is the value of a second variable:

eval var2=$"$var1"

Turns out a variable indirection feature has been around since bash 2! Sheesh!

var2=${!var1}

is the official way to do this. Alternately this should also do:

eval var2=\$${var1}
