this 'loose label' is one of the ugliest concept i can think of -)

i'm willing to implement anything reasonable but since i  hardly use
such math i only act on 'i want to achieve this' kind of specs (i have
no time to read tons of tex documents)

much if this 'complicated' math is not that complicated to support,see
attached file

btw, defaulting to numbers and then using \notag is messy; i prefer
readable code, even if it takes more  bytes;  inventing a formula takes
more time than keying it in.  Also, more structure,  means more hooks
for configurability
