I found an issue on expanding function calls from strings.
These makes me weep for my late Sinclair Spectrum's Basic.
It used to have a Function calles EVAL$ that could directly evaluate Functions entered by the user into a String.
The article above is on expanding an functions
existing somewhere in the current Perl file by using ${/ ...}.
Things like (Think of replacing "cos($i)" by <STDIN>..)

#!/usr/bin/perl use posix;# $i=3; $funk = "cos($i)"; print "Das ist ${\$funk}";

actually do'nt work properly.
Of cause I could generate an external Module on the fly and then reference to it. But it wold be a much deeper meditation on the special strength of interpreter languages to do it all inline.
**Ommmmm**
