It means, that [(a)] should contain a paren! containing a word as it did,
but (a)/(b) shall differ from (a) / (b), i.e. parens shall be treated
specifically - neither as possible word characters, nor as ordinary
Currently we have:
length? [(a)/(b)] ; == 3
, while I am proposing, that we should get:
length? [(a)/(b)] ; == 1
type? first [(a)/(b)] ; == path!
OTOH, it is OK to obtain:
length? [(a) / (b)] ; == 3
What do you think?
One may try to check an analogical situation: [a]/[b] versus [a] / [b]. What
would be the best solution in that case?

This case doesn't matter, any solution is acceptable to me.

I would suggest even less aggressive evaluation: if a word is evaluated,
, the result should be the same as the result of
with *exactly* one exception: if A is a function, then the function should
be evaluated in the former case.
I am sure, that this kind of word evaluation isn't incompatible with the
suggested path evaluation change.
