Anybody know what possible justification there could be for replacing 2 with H and so on in array literals (Table 1)? In general, a spec doc without an accompanying rationale doc seems emasculated.
"For example, [1H2J2j;YNG42A] gives [1 2 2 j 2j; inf NaN -j 42 5]."
Looks like the codes are to avoid printing spaces by alternating with digits. Ugh, but ok. Code golf. Sigh.
