in reply to Re^2: keys on scalar warnings and lack thereof
in thread keys on scalar warnings and lack thereof
I didn't explain %{ $_[0] }; I explained why %$_[0] is nonsense.
Maybe adding spaces and parens will help?
keys( %$_ ) keys( %$_ ) [0] Nonsense keys( %$ ); [0] `;` = End of statement keys( %$ ) # [0] `#` = Comment keys( %$ ) ^ [0] `^` = Binary op keys( %$ ) & [0] `&` = Binary op keys( %$ ) = [0] `=` = Binary op keys( %$ ) | [0] `|` = Binary op keys( %$ ), [0] `,` = Binary op keys( %$ ) < [0] `<` = Binary op keys( %$ ) > [0] `>` = Binary op
