Eval can be replaced by getfield in smooth

[julbinb]

getfield would be more efficient than eval in getting the value of a variable/function name here:

DSGE.jl/src/forecast/smooth.jl

Line 78 in e55b4dc

smoother = eval(Symbol(forecast_smoother(m), "_smoother"))

Toy example:

julia> using BenchmarkTools

julia> foo = 42
42

julia> @btime eval(Symbol("foo"))
  44.230 ns (0 allocations: 0 bytes)
42

julia> @btime getfield(Main, Symbol("foo"))
  1.180 ns (0 allocations: 0 bytes)
42

Thanks for this! This change will be added to the next release of the package.
