implement a new var @*ARGFILES listing paths for @*ARGS that are existing files #2666
Iterating over $*ARGFILES throws an error if the system tries to get a handle on a non-existent file.
Ability to iterate over only valid file handles as the name implies.
Throws on non-existent files.
Steps to Reproduce
Debian 9, 64-bit.
Create the new dynamic variable simultaneously with the creation of @*ARGS. It should contain the paths of the elements of @*ARGS that are existing, readable files.
What does "if the file exist" mean to different users? Does it exist at the time the program starts? Does it exist at the moment it is iterated over by
A naive solution:
