@balshetzer how about this?

fmm...

Hi. This change is good but I wanted to clean it up a bit. The first error message is not the same as the others, for example.

[hori-ryota]

OK. Is something better for me to do?

[hori-ryota]

@balshetzer Can I fix it? Let me know what you want to fix and I will try!

@hori-ryota The only mandatory thing I want fixed is for the error message on line 203 to be clearer. It should be similar to the other error messages.

Some nice to have improvements:

• the error case mentioned above should probably fail when the EXPECT call is first created.
• there are many error cases here. Can they be reduced?
• The condition on lines 222-223 is complex and not obvious. It might be good to have some comments with examples to explain the various situations it covers.
• alternatively, could the matching be rewritten to first handle all non-variadic args and then have a separate case to handle the variadic args? That might make the code easier to read.

How about my refactor?

Thanks!
