NAME

Eval::Compile - Perl extension for compile eval

SYNOPSIS

  use Eval::Compile qw(ceval cache_this cache_eval_undef);
  my $eval_string = '1+$a';

  for my $a  ( 1, 2, 3){
	  my $result = ceval( $eval_string ); # like eval only faster 
	  print $eval_string, " = ", $result, "\n";
  }
  # prints
#  1+$a = 2
#  1+$a = 3
#  1+$a = 4
	
  cache_eval_undef( ) ; # flush out current compiled eval cache

  # Simple results caching
  for my $b  ( 1,1,3,4){
	  my $r = cache_this( $b, sub { my $c = shift; heavy ops here ; return $heavy } ); # called only once for each $b
  }

  sub print_if_i_have_seen_this{
	  my $this = shift;
	  cache_this( $this, sub { print $this, "\n" }); #Stupid but efficient
  }
