Re: What's going on here?

perl -MO=Deparse,-p -e '120*312-77728+2.22772.224792222->x'
((-40288) + "\cB\x{58f4}\x{d660e9e}"->x);
[download]

Still asking why?

2.22772.224792222 is not a number, it's "version" string, i.e. three characters whose ords are 2, 22772, and 224792222. The -> operator is called on this string which interprets it as a class name.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

Good catch about the version string but I would only say `The -> operator is called on this string which interprets it as a class name.` It has nothing to do with version string, e.g. `42->x` does the same. I think.	[reply] [d/l] [select]

Yes, 42 is turned into the string "42" which is interpreted as a class name. Basically, anything that's not a reference is stringified by the arrow operator. Update: See The Arrow Operator in perldoc. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]
