• NAME
  
  ops - Perl pragma to restrict unsafe operations when compiling
• SYNOPSIS
  
  
    perl -Mops=:default ...    # only allow reasonably safe operations
  
    perl -M-ops=system ...     # disable the (Aqsystem(Aq opcode
  
  
• DESCRIPTION
  
  Since the <(>CW"ops" pragma currently has an irreversible global effect, it is only of significant practical use with the <(>CW"-M" option on the command line.
  
  See the Opcode module for information about opcodes, optags, opmasks and important information about safety.
