Hi Allen, could you remind me and a few others who were wondering
yesterday (sorry I don't remember -- it's in minutes, somewhere) why
[[Deletable]] was not chosen instead of [[Flexible]]? Thanks.
Deletable would match the other new names more closely in inverting
the sense of the ES1-3 attributes, avoiding Dont- prefixes which lead
to double-negative statements and the fuzzy meaning and marketing
connotations ("Agile!" ;-) of "flexible".

Special forms like var and function bind properties that are
DontDelete unless in eval code. Is this what Mark is getting at?
