Gem depends on #inspect producing valid Ruby code

[ngollan]

Trying to produce shorter/prettier (no accounting for taste) inspect output and overriding TrueClass/FalseClass#inspect breaks "optimisation" with something like:

undefined local variable or method `⊤' for #<Haml::AttributeCompiler:0x007f1a0304c648>

in Haml::AttributeCompiler#static_build.

I have true/false represented by "⊤" and "⊥" via

TrueClass.class_eval do
  def inspect
    "⊤"
  end
end

FalseClass.class_eval do
  def inspect
    "⊥"
  end
end

@ngollan do you have a sample of this override? Or, a gem that does this?

Having the attached code somewhere before Haml template compilation would reproduce this. It's my fault on Haml 5.

TrueClass.class_eval do
  def inspect
    "⊤"
  end
end

FalseClass.class_eval do
  def inspect
    "⊥"
  end
end

I had not expected this "issue" to get fixed ;-) Anyway, the test in the referenced commit overrides TrueClass#inspect twice instead of having one override for FalseClass.

Good eye! Fixed it b564537
