[julia-users] Symbols as Dict keys - efficiency / memory allocation?

[Oliver Schulz]

Hi,

I was thinking of using Symbols as keys in a Dict{Symbol,Int64}, instead of 
Strings. However, Symbol is not a bitstype, so there I guess there will 
still be a lot of individual memory allocation when working with such a 
Dict, right?

Actually, why isn't Symbol a bitstype (according 
to https://github.com/JuliaLang/julia/issues/5880, symbols are not GCed)?


Cheers,

Oliver
