The vecvec_apply_fn() function is a function factory that creates applies
the function .f to each vector and optionally simplifies the result with
[unvecvec()]. The function matches the forms of the original function
.f and can be used to define methods for generic functions that apply to
vecvec objects. If .f is a primitive function, the resulting function will
have a apply over an argument x and pass through ....
vecvec_apply_fn(.f, ptype = NULL, SIMPLIFY = !is.null(ptype))A function to apply to each vector
A prototype to simplify to. If NULL, the result will be a
vecvec object. If not NULL, the result will be simplified to the type
of ptype if possible.
If TRUE, the [unvecvec()] will be applied to the result
of vecvec_apply(), using ptype as the target type. If FALSE, the
result will always be a vecvec object.
A function that applies .f to each vector of a vecvec object and
optionally simplifies the result.
