__str__ method not found Error with ecr_embed on String::Builder.build on 0.11.0

[f]

String::Builder.build do |__str__|
    embed_ecr("hello.ecr", "__str__")
end

This code is broken on 0.11.0.

instantiating 'String::Builder:Class#build()'
in macro 'macro_4616040192' expanded macro: embed_ecr:1, line 1:

  1. __str__ << "Hello "
  2. (#<loc:"hello.ecr",1,10> env.params["name"] ).to_s __str__
  3. __str__ << "\n"

__str__ << "Hello "
^~~~~~~

undefined method '__str__' (If you declared '__str__' in a suffix if, declare it in a regular if for this to work. If the variable was declared in a macro it's not visible outside it)

Update

I solved with removing block.

__str__ = String::Builder.new
embed_ecr({{filename}}, "__str__")
__str__.to_s

And now I have another strange problem:

hello.ecr:

Hello <%= env.params["name"] %>

This is not working (says env is not unknown):

kemal.add_route "GET", "/view/:name" do |env|
  render "hello.ecr"
end

This is working:

kemal.add_route "GET", "/view/:name" do |temp_env|
  env = temp_env
  render "hello.ecr"
end

What about String.build instead of String::Builder.build ?

@f Thanks for reporting this!

This and #2050 are probably worth a minor release with these fixes (0.11.1). All of these regressions are because of these two bug fixes: 81a7af2 and 92aabbd. There was a big chance that they introduced new bugs.

@ysbaddaden Same.
