It's things like this, and executing vars and such, that made me drop Eu for a 
number of things. You could just as easily encorporate dynamic includes as:

var = fget("filename.e")
function1 = var[50..2000]
function2 = var[2010..3000]

or 

execute(var)

But heck, i have been screaming for these things for years, i am now using 
PHP to get around Eu deficiencies, especially on nix boxes. You may be 
deciding on what the language can do based on the number of people asking 
for them, but you won't hear from those who just decide you won't add them 
anyhow, and politely quietly move on to other languages. At least i said 
something first, repeatedly. People won't use it if they must first ask for 
features, wait years, and then see if they get the features. Or get Karl to add 
it to his language in a few days.
