Yes,
Rem is based on set_trace_func and SCRIPT_LINES__.

Rem is very slow, maybe more slower than debug.rb.
I use time command (on zsh) to check how slow rem is.

  % cat hello.rb
  
  printf("hello, world\n");


  % time echo "cont" | ruby -rdebug hello.rb
  ...
  echo "cont"  0.00s user 0.01s system 167% cpu 0.006 total
  ruby -rdebug hello.rb  0.13s user 0.01s system 101% cpu 0.138 total


  % time echo "cont" | rem hello.rb
  ...
  echo "cont"  0.00s user 0.01s system 61% cpu 0.016 total
  rem hello.rb  0.43s user 0.05s system 102% cpu 0.470 total
