ERB#result does not accept a proc, the documentation says:

> Executes the generated ERB code to produce a completed template, returning the results of that code. 
> (See ::new for details on how this process can be affected by safe_level.)
> b accepts a Binding object which is used to set the context of code evaluation.

However, #result delegates to Kernel.eval, which says:

> Evaluates the Ruby expression(s) in string. If binding is given, which
> must be a Binding object...

When given a proc, #eval errors with:

> ruby-2.1.1/lib/ruby/2.1.0/erb.rb:847:in `eval': wrong argument type proc (expected binding) (TypeError)

I verified on 2.1.1 and 1.9.3p484

Patch included.
