New submission from Serhiy Storchaka:
Two new opcodes BUILD_MAP_UNPACK_WITH_CALL and BUILD_TUPLE_UNPACK_WITH_CALL
(added in 3.5 and 3.6) have too long names (26 and 28 characters). This exceeds
the width of the opcode names in the dis module (20 characters). Increasing the
width of the column will make opcode arguments too distant from opcode names,
that will decrease readability. The better solution would be renaming these two
opcodes.
They are used for merging iterables and mappings of positional and keyword
arguments when used var-positional (*args) and var-keyword (**kwargs)
arguments. Maybe new names should reflect this.
>>> dis.dis('f(a, b, *args, x=x, y=y, **kw)')
1 0 LOAD_NAME 0 (f)
2 LOAD_NAME 1 (a)
4 LOAD_NAME 2 (b)
6 BUILD_TUPLE 2
8 LOAD_NAME 3 (args)
10 BUILD_TUPLE_UNPACK_WITH_CALL 2
12 LOAD_NAME 4 (x)
14 LOAD_NAME 5 (y)
16 LOAD_CONST 0 (('x', 'y'))
18 BUILD_CONST_KEY_MAP 2
20 LOAD_NAME 6 (kw)
22 BUILD_MAP_UNPACK_WITH_CALL 2
24 CALL_FUNCTION_EX 1
26 RETURN_VALUE
