What about adding #from: ? I want it to be terse and still clear if
possible.

Well, it's there because a hash table needs more room than it has
elements. In fact I'm about to add
HashedCollection >> withAll: x
| result |
result := self new: x size * 2.
result addAll: x.
^result
It does not apply to with:with: and friends only because of
new: anInteger
"Answer a new instance of the receiver with the given size"
| realSize |
realSize := 8 max: anInteger.
...
^(self primNew: realSize) initialize: realSize
