[Tarantool-patches] [PATCH v3] test: flaky box/net.box_wait_connected_gh-3856

[Alexander Turenko]

LGTM.

I have a few comments, but it is just for appearance, nothing critical.
No need to re-review with me if you'll change it in the proposed ways.

WBR, Alexander Turenko.

It is not necessary anymore: you can just use backslash and don't use
delimiters. Up to you, but this way is shorter and looks more elegant.

It looks okay, but we can do it without defining a function.

 | do                      \
 |     local c = <...>     \
 |     local res = c.state \
 |     c:close()           \
 |     return res          \
 | end

Up to you.
