Well it would be easier to implement in an interpreter than in a compiled 
version!

It is a very different animal to Euphoria, but it might be worth looking 
at what NoteTab does. It substitutes variable names by their values into 
the "source line" and then rescans and does the same again as often as 
required. This does allow some very clever stuff to be done and I for one 
would like to have some such facility.

But making a compiled version of that is rather trickier as I said because 
usually the variable names are gone by then, but in this case they could 
not be.

Is there already a general facility in Euphoria to access a variable from 
having its name in a string?  This is a useful capability to have. There 
is one Euphoria command/proc/function that has the variable name as a 
parameter in quotes - I forget which one.
