Re: Variable Namespace Best Practice Question

Well, since you asked, I'd say the preferred method would be this:

sequences lines = read_file(myfile) 
for line in lines do 
... 

But that'll have to wait. So I would prefer this:

sequence lines = read_file(myfile) 
for i = 1 to length( lines ) do 
    sequence line = lines[i] 
... 

Performance-wise, there really won't be a difference, because the backend is going to reserve memory and reuse for each assignment.

So you don't incur the penalty of repeated malloc/free calls. And there's an advantage to keeping the variable private to the scope of the for loop.

P.S. read_lines() returns separate lines. read_file() returns the whole file as one big string.

P.P.S. I think you meant "scope" instead of "namespace"
