Well, the first idea was that it given that a StrikeFont can already 
swap glyphs (#useUnderscores, #useLeftArrow), then it is possible to 
build cheap derivative fonts that do that, and TextStyles for them. 
Then, Shout parses code and sets TextEmphasis like italics or colors for 
differenc code elements. I just made it set a TextEmphasis with 
underscores for identifiers.

It is so simple that I find it surprising that nobody (including me) 
thought about this years ago!
