We once had outer. The outer solution looked like this:
for_each(_1, lambda [ push_back(_1, outer(_2)) ] )
How would that look like if you extend phoenix with your syntax?
It would be good to tackle this through practical use-cases and using plain C++ terms. Too much formality hurts my brain. If this use-case is too simplistic, then perhaps you can provide something more elaborate, yet still practical.
Actually that is pretty close to what I was describing, but imagine outer being like this to indicate how many levels up to go: for_each(_1, lambda [ push_back(_1, outer<1>(_2)) ] ) Then simplify the syntax by doing something like outer<1,2>, which could then have a predefined value called _1_2 or so... I like outer, guess it would be fully powerful if it could specify how many 'outer' levels to go out to with a template param like the above?
