Looking at making some changes to a module that loops over an array (actually a list, handed off from a file handle, where I'd like to loop on the handle itself).

Internally, do for() and while() do the same thing, ie., are the following equivalent?:

for (<$fh>){
    print;
}
while (<$fh>){
    print;
}

With that simple example, they seem to do the same thing (in v5.22 on Linux Mint at least). But below the surface, do they really?
