The following doctest failure seems to be related to your previous commit:

File "src/sage/interfaces/tides.py", line 695, in sage.interfaces.tides.?
Failed example:
    l[30]
Expected:
    '\t\tmpfrts_pow_t_c(itd, link[2], "-1.500000000000000000000000000000000000000000000000000", link[3], i);\n'
Got:
    '\t\tmpfrts_pow_t_c(itd, link[2], "-1.500000000000000000000000000000000000000000000000000", link[{i}], i);\n'

Now there is this one:

File "src/sage/interfaces/tides.py", line 691, in sage.interfaces.tides.?
Failed example:
    l[15]
Expected:
    '\tstatic int PARAMETERS = 0;\n'
Got:
    '\tstatic int PARAMETERS = 4;\n'
**********************************************************************
1 item had failures:
   1 of  95 in sage.interfaces.tides.?
    [120 tests, 1 failure, 0.09 s]

Probably caused by this change (PAR -> VAR):

-    outfile.write("\tstatic int PARAMETERS = {};\n".format(PAR))
...
+        outfile.write(f"\tstatic int PARAMETERS = {VAR};\n")

@miguelmarco, can you check that the generated files are still good for the TIDES library? (not necessary any more).

BTW: The workflows that run doctest of optional and experimental packages seem to be broken (at least the ones that run for the tag 10.2.beta9, example for Ubuntu jammy maximal is failing here).

Is this a known issue?

Documentation preview for this PR (built with commit 0a81064; changes) is ready! 🎉

LGTM!

The generated files of the examples are not changed by the branch.

Anyway, the idea behind E221 is not clear to me. Looking through the changes my impression is that it makes code less readable.
