Hi,

irb(main):001:0> begin ; $SAFE=2 ; end ; puts $SAFE

irb(main):002:0> puts $SAFE

irb(main):003:0> def s ; $SAFE=2 ; end ; s ; puts $SAFE
2
irb(main):004:0> puts $SAFE
0
irb(main):005:0> eval "$SAFE=2; puts $SAFE" ; puts $SAFE

rb(main):007:0> eval "$SAFE=1; eval '$SAFE=2; puts $SAFE' ; puts $SAFE" ; puts $SAFE

Obviously, $SAFE will be reset after `eval' expressions have
completed. Are there (besides threads) other cases where
$SAFE is reset? And if not: why will it be reset after
every `eval'?

Thanks in advance,

Bertram
