Proc#>> and << are not supported

[deepj]

This is a new feature in Ruby 2.6. The proc's function composition is used in dry-monads spec when 2.6 is available. See https://github.com/dry-rb/dry-monads/blob/6ca973c87c65e1526bfd4b671a8229319ce00bb1/spec/unit/maybe_spec.rb#L53

This causes some troubles to run some specs in TruffleRuby "supporting Ruby 2.6"

Yes, spotted that one. 😄

There's a couple of other small issues that need fixing as well.

@aardvark179 yeah, I know about them. I don't report everything :) This issue is reported after ~2 months what I know about it.

@eregon @chrisseaton Hello, can you make this priority since this uses a lot of specs in dry-types/dry-schemas, please?

[chrisseaton]

Fix on the way.
