OpenEuphoria

And that "works" in v4 (gives no error), but doesn't work the same way because any call to "task_schedule" (which is global) outside this file will still call the built-in, unless I declare this version "override" instead of global. (If called from a later point within the same file, it works as before.) Since no error is given and no crash is guaranteed, this could lead to some nasty bugs with converted programs.

Anyway, I know I've got a few of these around in my libraries, and I can think of some others in 3rd party libraries (i.e. Method Euphoria). But there may be some I don't remember. Any easy and foolproof way to find them? I think there are a few programs around that will list all your declarations, or is there a tool somewhere I don't know about? (I normally don't use IDEs or anything, just pure TextPad w/ syntax highlighting.)

Also, a related question that also could cause some weird problems with converted programs in rare cases:

In v4 you are allowed to call a function that is declared later in the file, but if it is a built-in it will prefer the built-in. If it is a user-declared function, it will prefer the local version (declared below) even if there is a global version declared in another file (which is included "above"). This seems a bit inconsistent, but whatever, do I have this right?

In other words:

puts(1,"Hello") 
 
override puts(integer i, sequence s) 
   eu:puts(i,s) 
   eu:puts(i,"\nOVERRIDDEN PUTS!\n") 
end procedure 

The above will just output "Hello" since it prefers the built-in. (Works the same as v3.1 if "override" is changed to "global".)

Also, I didn't test it, but I assume if I do a routine_id("myputs") in that same spot I'm going to get the routine number for the same version as it is calling in that spot? (It is likely that any such problems caused by these new scoping rules with old code will involve a routine_id.)

Any good way to track these traps down so I can run my old programs safely? (And yes, what may be "rare" might not be so rare with me because I do all kinds of crazy stuff with routine_ids and overriding of built-ins.)
