[julia-users] Why construction of Dict via generator is not type-stable?

2016-11-13 Thread bogumil . kaminski
Consider the following two functions: function f1(t, a) [t(x) for x in a] end function f2(t, a) Dict((x, t(x)) for x in a) end When I run @code_warntype on them I get: julia> @code_warntype f1(sin, [1.0, 2.0]) Variables: #self#::#f1 t::Base.#sin a::Array{Float64,1} Body: begin

What about storing eltypes in variables and directly calling 'Dict{eltypa,eltypet_a}(...)'? I think there is some issue about this github too.

Until the issue with generators is resolved, this may suffice: f2x{T}(t::Function,a::AbstractArray{T})::Dict{T,T} = Dict((x,t(x)) for x in a) I think that diverts all the ambiguities to checks by conversion methods. On Sunday, November 13, 2016 at 11:16:20 AM UTC-5, bogumil@gmail.com wrot
