Subject: variable expansion inside string

Hello, is it possibile to do only variable expansion inside a string, eg:
file="filename.txt"
a="*$file*"
I would like to print $a as:
*filename.txt*
I have tried ${(P)a}
and
eval echo -n - $a
but neither do what I would like, because $a does not contains only a
variable name, and the * are expanded by glob subst in the eval case.
thanks in advance
