Is the behavior of `macrocase` right?

[me-kell]

macrocase("My URL") returns MY_UR_L (note the underscore between R and L). I would expect MY_URL

Regarding the word boundaries I would expect a result similar to cobolcase, snakecase, and kebabcase.

cobolcase("My URL") returns MY-URL

>>> from caseconverter import *
>>> cases = [str, macrocase, cobolcase, kebabcase, snakecase]
>>> for case in cases:
...     t = f"{case.__name__: <15}"
...     for s in ["My New URL", "My NewURL", "My URL", "My IP", "My MACRO"]:
...         t += f"{case(s): <15}"
...     print(t)

str            My New URL     My NewURL      My URL         My IP          My MACRO
macrocase      MY_NEW_UR_L    MY_NEW_U_R_L   MY_UR_L        MY_IP          MY_MA_C_R_O
cobolcase      MY-NEW-URL     MY-NEW-URL     MY-URL         MY-IP          MY-MACRO
kebabcase      my-new-url     my-new-url     my-url         my-ip          my-macro
snakecase      my_new_url     my_new_url     my_url         my_ip          my_macro
