Fredrik labeled the controlled dimension "readability".
As I understand the description, it specifically has to
do with accessibility for *beginners* in a language.
This inspires two reactions:
1.  We need a word to distinction the quality
    that people-who-don't-already-know-it-can-
    read-it.
2.  Maybe this'll help sharpen the sniping
    between proponents of Python and Java
    syntaxes about how the latter is slanted
    *too* much toward newbies.
