Thanks for the explanation of dyadic ?.

On ⍎ and ⎕FIO, I guess currently it’s pointless to try improving the 
performance of ⍎.  For strto* family, perhaps an interface like (Zn Zs)←⎕FIO[X] 
Bs calling Zn=strto*(Bs, Zs) would suffice for most of the use cases?  scanf 
family would need extra work similar to printf which looks into the string and 
arrange for appropriate cells.

A simple function like Dyalog’s ⎕VFI [1] would be great, but not necessary.
