|Priority||normal||Severity||feature||Reproducibility||have not tried|
|Target Version||Fixed in Version|
|Summary||0005792: request for Weak.set_some function|
|Description||Could we get the following function added to the [Weak] module?|
val set_some : 'a t -> int -> 'a -> unit
It would satisfy the equation:
set_some t i a = set t i (Some a)
but would have the benefit that one is not forced to allocate a [Some]
|Tags||No tags attached.|
I would be also glad also to have such a function.
1) It is not practical to implement it as a normal programmer, because one needs access to .h files that are not installed by the compiler.
2) It is a trivial addition.
3) I tried it (by modifying directly byterun/weak.c), and on a benchmark where I used to Weak arrays for memoization (modification of Filliatre BDD library), I gained 10%.
