method close§

method close(IO::CatHandle:D: --> True)

Closes the currently active source handle, as well as any already-open source handles, and empties the source handle queue. Unlike a regular IO::Handle, an explicit call to .close is often not necessary on an IO::CatHandle, as merely exhausting all the input closes all the handles that need to be closed.

with IO::CatHandle.new: @bunch-of-handles {
    say .readchars: 42;
    .close; # we are done; close all the open handles
}
