( #3333=superdoc: print w/ replies, xml ) Need Help??

The strange thing is that although $fh->can('close') doesn't return true, it also doesn't complain about there being no can method, whereas $fh->might('close') does complain about a missing might method. So it is, in some manner being treated as an object that kinda half implements the UNIVERSAL interface.

Writing the empty string to a handle is quite a nice solution I suppose, but there may be some tied interfaces where printing even the empty string has side-effects. :-(

And as it happens I'm actually more interested in reading than writing.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
