Seems like an obvious issue that has been considered during implementation of this cop, but couldn't find any duplicates searching for "map to_h", so reporting just in case.
Steps to reproduce the problem[1, 2, 3].map { it * 10 }.to_h do
[it, it * 100]
end.then { pp it } Actual behavior
Says Style/MapToHash: Pass a block to to_h instead of calling map.to_h.
Replacing map with to_h will obviously break the code, as to_h belongs to its following block
The message could implicitly hint at merging the code like so, but this requires some lenience on the reader's part.
[1, 2, 3].to_h do
it *= 10
[it, it * 100]
end.then { pp it } Expected behavior
A) Whitelist it (preferably)
B) Suggest something like "merge the blocks", but original code might be perfectly acceptable for clarity (so rather not)
