lastindex method error in 1.0 #20

Closed ayush1999 closed 5 years ago

ayush1999 commented 6 years ago 
>>> vcall(a...) = DataFlow.vertex(DataFlow.Call(), DataFlow.constant.(a)...)
>>> a = vcall(:+, 1, 2)
>>> b = vcall(:- , 1, 2)
>>> c = vcall(:* , 1, 2)
>>> d = vcall(:+, a, b, c)
>>>d[1:end]

On julia0.6, The output is:

julia> d[1:end]
4-element Array{IVertex,1}:
 IVertex(+)    
 IVertex(1 + 2)
 IVertex(1 - 2)
 IVertex(1 * 2)

But on julia1.0, we get a methoderror:

>>> d[1:end]
ERROR: MethodError: no method matching lastindex(::IVertex)

  lastindex(::Core.SimpleVector) at essentials.jl:577
