   ALGOL 60 is one hell of a programming language what do you mean they were doing this call by name nonsense in 1960

     they still had fucking index-register-less vacuum tube computers and they go "hmm yes the best way to program this is with the most complex evaluation strategy known to man"

     @koakuma procedure arguments in ALGOL 60 (and derivatives) are by default passed as like a thunk that will return the value instead of being evaluated at call point, it’s evaluated whenever it needs the value
     for instance this thing

     real procedure Sum(k, l, u, ak) value l, u; integer k, l, u; real ak; comment k and ak are passed by name; begin real s; s := 0; for k := l step 1 until u do s := s + ak; Sum := s end;

     and you can do Sum(i, 1, 100, V[i]) (given a 100-element array V and an integer variable i) and it’ll ask for the value of V[i] after setting i to the loop variable on each iteration
