## Our powform's binary-positional convention''First child is base, second child is exponent'' for 32 markup seems natural and easy to memorize

## But without some kind of 'signature declaration'this markup could instead mean 23 according to a''First child is exponent, second child is base'' convention

## Analogous conventions for N-ary operators (N ɮ) need to disambiguate a combinatorially exploding number of possible interpretations

## Without extra information the positions of 'roles' (powform: base and exponent) of children cannot in general be determined from some such markup
