This code causes a syntax error: 
#!/usr/bin/perl
use strict;
grep {
 NUM:
  for(0 .. $_)  {
    last NUM if $_ > 3;
  }
}  1 .. 10;

syntax error at ./test.pl line 4, near "NUM:"
syntax error at ./test.pl line 8, near "}"
Execution of ./test.pl aborted due to compilation errors.

One fix is to put something in front of the label: 
#!/usr/bin/perl
use strict;
grep {
  1;
 NUM:
  for(0 .. $_)  {
    last NUM if $_ > 3;
  }
}  1 .. 10;

Is there any way to start the block with a label?
