Re: Simple Pass By Reference

Pardon me for being so dense, but

  DB<1> sub altervar { $_[ 0 ] =~ s/a/b/g }
  DB<2> $var_elsewhere = 'aaa'
  DB<3> altervar( $var_elsewhere )
  DB<4> p $var_elsewhere
bbb

This solution seems too trivial. What am I missing?

Update: Thanks to BrowserUk++ for pointing out the requirement I missed.

From the OP's update: I'd also like to use a meaningful name rather than $_[0] throughout the subroutine.
