( #3333=superdoc: print w/ replies, xml ) Need Help??

but the more correct way is to think of run-time and compile-time as a per-block thing.

Quite so, ++ (Per-statement, even, in the case of use.)

print("first"); BEGIN { delete $INC{'ModX.pm'}; use lib '../'; use ModX; } print("last");

gets executed in the following order

use lib '../'; # Before "delete" because of "use" use ModX; # Before "delete" because of "use" delete $INC{'ModX.pm'}; # Before "first" because of "BEGIN" print("first"); print("last");

In detail:

  1. Compile print("first");.
  2. Compile BEGIN { ... }.
    1. Compile delete $INC{'ModX.pm'};.
    2. Compile use lib '../';.
    3. Execute use lib '../';.
    4. Compile use ModX;.
    5. Execute use ModX;.
  3. Execute BEGIN { ... }.
    1. Execute delete $INC{'ModX.pm'};.
  4. Compile print("last");.
  5. "Run phase" starts.
  6. Execute print("first");.
  7. Execute print("last");.
