Overview

A dedicated per-render binding host. bf and v are the ONLY locals a compiled template may reference (see the class docstring); giving each render its own tiny object (rather than reusing a shared binding) means concurrent / nested renders never see each other's v.

def render(template)
  # `bf` / `v` must be real LOCAL variables (not instance
  # variables) at the point `binding` is captured -- ERB templates
  # reference them as bare identifiers (`bf.h(...)`, `v[:x]`), and
  # `Binding` only exposes locals in scope + the object's own
  # instance variables under their own `@`-prefixed names.
  bf = @bf
  v = @v
  template.result(binding)
