I have a stack of objects that changes size. It never gets very large, but
it varies in size a lot. Much of my program's time is spent creating
objects to push onto the stack and then GCing them when they are popped.
This seems like an obvious place to do some kind of manual pooling of
If you have an array of immutables you can replace the elements with new ones:
julia immutable Immut
x::Int64
y::Float64
end
julia a = Array(Immut, 5)
5-element Array{Immut,1}:
Immut(140562692057328,6.9447197253385e-310)
Immut(493921239054,6.94471970408933e-310)
