Hi

what exactly is the application/motivation/benefit for the way perl numifies strings?

  DB<9> $x="abc"
 
  DB<10> p 5 +$x
5
  DB<11> $x="2abc3"
 
  DB<12> p 5 +$x
7

BTW: This behaviour seems only to be documented for unary - in perlop

  DB<18> $x="ab2c3"
 
  DB<19> p -$x
-ab2c3
  DB<20> $x="6ab2c3"
 
  DB<21> p -$x
-6

Isn't this behaviour mainly hiding ugly bugs?

Cheers Rolf
