Unfortunately, it is not always that simple, because there are regressions in
Euphoria.
The most obvious one is that, under 2.4 and earlier, you could define at run
time the contents of a file to be included, which was a way to implement dynamic
code. A little unwieldy at times, but it worked. This feature disappeared with
2.5. Try defining the contents of a file before including it: this is legal, but
the file has been read and parsed before the statements that set its contents are
executed. Hence you need two Eu programs, one to set the file contents and then
the main program. And it gets messier if the two processes need to exchange
information. A typical application is when include files are different depending
on some hardware/OS configurartion, and the main program also needs the info.
Again, it can be done using editor scripts to update the main program before
running it, but this is definitely harder than the previous way.
