hELLO,
$@ is a system variable that return error messages. If our statement
executed by the eval function (eval 'exec perl $0 -S ${1+"$@"}')
contains an error, or an error occurs during the execution of the
statement, the error message is stored in $@.
I.e:
eval ("This is not a perl statement");
assigns $@ with :
syntax error in file (eval) at line 1, next 2 tokens "This is"
