This is mentioned in my copy of the Camel (the most recent ed. whichever that is). Taint, blessedness and all the other little things that make perl scalars neat do not apply to hash keys coz they're just plain old strings. Hash keys are not scalar values.

I tried to find some good documentation to support myself with, but this is clearly not well documented behavior. Dominus mentions it in his September 1 1998 Line of the day (scroll down). There's also a note in an old version of the Taint module. I couldn't find anything more recent. But it is in the latest Camel, I don't have my copy handy or I'd find a page # for ya.
