Expression Interpolation from input "template string"?

[Peter Fitzgibbons]

Hello all,

I have a set of "template messages" from a database table that I want
to go something like this :

"Hello, today is #{msgDate}"

What I don't know is how to get the interpolation to work when the
string is read from teh database as if :

x =3D 'Hello, today is #{msgDate}' <<=3D=3D note the single quotes

Have any ideas ?

Thanks.
