content_for recursive array join error, rspec fails with slim

[penguinstampede]

after updating my bundle, I am running into this error:

ArgumentError at /
recursive array join

When running rspec on sinatra-contrib, there are 40 failures and all relate to slim... most of the failures are in content_for.

rspec ./spec/content_for_spec.rb:179 # Sinatra::ContentFor Erb with yield_content in Slim renders blocks declared with the same key you use when rendering

also, the bundle, fwiw:

Very likely this is a duplicate of #67.

Just a note.

The "recursive array join" error show only with slim (2.1.0).

After updating to slim (3.0.0), that has the dependency on temple (0.7.3), the error changes to
undefined method <<' for nil:NilClass`.

nice find, thanks very much. moving back to temple 0.6.8 does clear up all of the rspec errors.

[penguinstampede]

Decisions! Need to move past Temple 0.6.8 if I want to use the Slim includes plugin. But, still getting the "recursive array join" error using content_for with Temple 0.7.5.

Does that make this a Temple issue or a Sinatra-Contrib issue?
