It turns out that `:4_to_5=` is not a valid symbol but `"4_to_5=".to_sym` does not quote it and represents it as `:4_to_5=`, which throws off our whole method name validation logic. The fix is to check validity of the name after stripping trailing `=` as well. That leaves `==` as an edge-case, that we handle separately.

Our current way of doing method name and parameter name checks are a bit hacky and [that's been showing through](#1045). A better way to do this is to use the compiler to do the name checks, similar to [how Ruby does it in its codebase](https://github.com/ruby/ruby/blob/241dced625f9ba8a4071954579778a0940e75179/ext/rubyvm/lib/forwardable/impl.rb#L3-L9). This method relies on compiling a method definition with the given name and then checking if the compiled code actually defines a method with that name.

Motivation
Fixes #1042
It turns out that
:4_to_5=is not a valid symbol but"4_to_5=".to_symdoes not quote it and represents it as:4_to_5=instead of:"4_to_5", which throws off our whole method name validation logic.The behaviour of Ruby was correct on this symbol until
ruby-2.2.0-preview2, after which it was broken:I think it is related to this change: ruby/ruby@986a893
Implementation
The fix is to check validity of the name after stripping trailing
=as well. That leaves==as an edge-case, that we handle separately.Tests
Improved existing tests and added explicit AR column tests for invalid method named column names
