Now with CACHE entries, the lasti could point to a CACHE entry and current line indicator will be confused.

import dis def f(): print(a) dis.disco(f.__code__, lasti=2) dis.disco(f.__code__, lasti=4)

will display

 3 0 RESUME 0 4 --> 2 LOAD_GLOBAL 1 (NULL + print) 14 LOAD_GLOBAL 2 (a) 26 PRECALL 1 30 CALL 1 40 POP_TOP 42 LOAD_CONST 0 (None) 44 RETURN_VALUE 3 0 RESUME 0 4 2 LOAD_GLOBAL 1 (NULL + print) 14 LOAD_GLOBAL 2 (a) 26 PRECALL 1 30 CALL 1 40 POP_TOP 42 LOAD_CONST 0 (None) 44 RETURN_VALUE 

This is confusing for the users because they would probably not realize that there are CACHE entries. And with show_caches=False, we should show the current line to the instruction that the CACHE belongs to.
