What I want to do is to have my own sub language entered as
string. The string contains a command, expressions and also
variables of the actual scope, which will be read or written to.
Therefore I need string mixins. I just wonder wheter there is a
possibility not to write at every place
"mixin(interpret("..."));" but a nice statement like
interpret!("...");

Kind regards
