The following code works on 0.5, but not on 0.6 (0.6.0-pre.alpha.0) macro macroex(n) :(println($n)) end type MWE nvar :: Int x0 :: Array{Float64,1} function MWE(nvar) x0 = zeros(nvar) @macroex nvar # <-- Fails here return new(nvar, x0) end end function foo() @macroex 5…

You need $(esc(n)) in the macro; see the macro hygiene section of the manual.
