Hi Alex,
Following the design proposed by Stef, in your case you would use a different
collection.

Hi Stef,
You are raising an interesting point to discuss. This MissingValue is indeed
better than having -1
Something to keep in mind: it may be that one would like to focus on the
missing value and not really the value.
Consider:

Hi,
MissingValue (or NoValue) is definitely the way to go. The
UniformOrderedCollection is an interesting idea, too. We had a NoValue like
solution a long time ago but we discarded because we missed the idea around
collections. It would be really cool to have this working.
Cheers,

So basically you are trying to deal with missing values in collections.
People working with R or Python data analytics framework made some
ways to work with specific data structures called dataframes
where you can have some missing values.
For example you may have a look here:
I'm currently trying it and it seems quite easy to load and use - just
working fine.
Of couse it seems kinda slow in comparison with native implementations (2000
iterations of SHA256 into 32 byte hash taking almost a second on my quite
powerful PC), but that's expected and not that much of a
Hi dear great OO designers
Here is a little challenges for your brainy souls :)
In Moose when we compute metrics it may happen than a tool (often external
to pharo) does not compute a metrics
and when we request it in moose we check and often we return a not so good
-1.
I'm trying to
In a 4.0 image I got in a situation where it seems Ring is out of sync (I am
getting errors of missing meta classes on each accept). I vaguely remember
there being an expression to reset/reinitialise Ring ?
Does anyone remember ?
Thx,

Yes this is why it would be a good addition to protego
