Hi

it's possible to alias a scalar to an element of a hash 

  DB<38> *y =\ $h{y}


  DB<39> $h{y}=666


  DB<40> p $y
666

  DB<41> $h{y}=42


  DB<42> p $y
42

but I failed doing it the other way round. (i.e. $

Q1. Is it possible?

I could Tie::Hash the complete hash, but this would slow down all fetch operations on the hash, not only the aliased elements.

Q2. can I Tie::Scalar only a single element of a hash?

Thanks for insights! :)

Sorry I'm stupid, my code already does what i wanted...

  DB<53> $h{z}=111


  DB<54> *z= \$h{z}


  DB<55> p $z
111

  DB<56> $h{z}=222


  DB<57> p $z
222

  DB<58> $z=333


  DB<59> p $h{z}
333
