Hi Anonymous,

Actually there's still a bug in there, you'll still get the same "Argument ... isn't numeric in addition" warning when Read fails. warn "message... ".0+$obj_temp is interpreted by Perl as warn "message... 0" + $obj_temp; (i.e. the concatenation happens first) instead of what you want, warn "message... ".(0+$obj_temp). Try it yourself: perl -MO=Deparse,-p -e 'warn "message... ".0+$obj_temp'

The reason is the operators + and . have the same precedence but are left associative (compare the output of the aforementioned Deparse with this: perl -MO=Deparse,-p -e 'warn 0+$obj_temp."message... "'). You should use parentheses to set the precedence and for clarity.
