If you are potentially assigning quotes, special shell characters and spaces, I would suggest a slightly different approach.

export foo=bar
printf -v "baz$foo" '%s' "wibble"
echo $bazbar

Works better for odd things like the following.

printf -v "test" '%s' "'single' and"'"double" quotes, '"\nnewlines, backslashes\\ and much more"'!'
echo -e "$test"

Sorry, also forgot about this:

foo=bar
bar=baz
echo $foo    # bar
echo ${!foo}    # baz
