that should be:
isimmutable(T::DataType) = !T.mutable
You could add more cases for the other Types (Union, TypeVar, and
TypeConstructor), although whether you need that in practice would be
determined by your use case. Tuple isn't a special case type since mid-2015
(during v0.4-dev)

Nice :)
Slight (10% or so) performance regression in Tests.runAll() here:
https://github.com/fncodr/tblous/blob/master/src/Tests.jl
The linked code is mostly focusing on array allocation and copying, and the
regression is consistent for several different code paths.

Hi,
I've been experimenting with binary searched sets & maps in Julia. Managed
to squeeze out an alternative symbol implementation based my map
implementation that could be useful when sorting by name a lot. Any
pointers/ideas on how to optimize this further or improve the code are most
welcome

5-element Array{Float64,1}:

julia> a[1:3][1:2] = 1.0
1.0
julia> a

0.0
0.0
0.0
0.0
I understand that `a[1:3]` creates an extra array and then `a[1:3][1:2] =
1.0` modified the extra array rather than the origin `a`
this is really nice; thank you for putting this package together.

Has anybody else come across this?
I am no longer able to build from master due to this:

I was implementing a bunch of Runge-Kutta tableaus and ran into an issue.
Specific tableaus which are defined inside of a function inside of
DifferentialEquations.jl cause segfaults, but those exact same functions
will not segfault when not inside the package. For example, the code (on
master):
There is a way -- after the weekend.

Yes, the call to `map` is type-unstable on 0.4, with a return type inferred
as `Tuple{Any, Any, Any}`. It seems fine on 0.5.

That creating a new Element allocates is not strange because it creates an
array. The map call might allocate due to higher order functions not being
optimal in 0.4.
My guess is that Julia cannot determine all the types of the variables and
expressions used in this first if statement. This is surprising, because it
should. I've tried locally with Julia 0.4 and Julia 0.5, using
code_warntype and code_native, and couldn't find a problem.
Which Julia version are
Whops, the copy paste got messed. Here it is,
typealias ElementSize Tuple{Int, Int, Int}
