If Knuth only intended to invent markup languages in his spare time, and did not 
intend to split the difference between developer-facing and customer-facing 
verbiage, then we are beyond literate programming.

Here's an example of a test case written in programmer-speak:

   test_strobe_count_down_fields_in_pre_fight_states

Now reverbiage it:

   specify 'the audience sees an animated countdown before the fight' do

Figuring out how to say an internal detail in terms a client can understand is 
often brain-wrenching. As developers, our brains are prepped with developer 
terms. The B in BDD stands for "Behavior the client has requested"...
