Foreach $Tmp (@Arr){

Please is it a bug ? Any documentation may help me to treat this problem

This is not a bug. You have run into filehandle buffering in which the
print is held in a buffer and not displayed on the screen until the buffer
is full or dumped. In the case of printing to STDOUT it is dumped when it
sees a newline. You can turn off buffering using the $| variable. See
perlvar for details.
A gentle tutorial on buffering and how to deal with it in Perl can be
found

You are wicked and wrong to have broken inside and peeked at the
implementation and then relied upon it.
