Safe in that it won't cause problems w/ other's work --with Gems, for
instance.

Thanks. Yes, I discovered soon after posting. Here's my current verson:

  require 'uri'

  module Kernel

    alias_method :require_prefacets, :require
    def require( *args )
      require_esc( *args )
    end

    def require_esc( fpath )
      fs = fpath.split('/')
      fn = fs.pop
      dn = fs.join('/')
      dn += '/' unless dn.empty?
      en = URI.escape( File.basename( fn ), /[^.-_\w]/ )
      require_prefacets( "#{dn}#{en}" )
    end
    alias_method :require_facet, :require_esc

  end

Works much better. Should there be any error caching on this sort of
thing?
