I feel we should either differentiate them or integrate them better, they
are not listed anywhere, Steffan provided a complicated way of getting a
list of those:
function builtins()
nams = filter(s -> isdefined(Base, s), names(Base, true, true))
objs = map(s -> Base.(s), nams)
funcs = filter(x -> isa(x, Function) && isa(x.env, Symbol), objs)
convert(Vector{Symbol}, sort!(map(symbol, unique(funcs))))
end
julia> builtins()
22-element Array{Symbol,1}:
:_apply
:_expr
:applicable
:apply_type
:arrayref
:arrayset
:arraysize
:fieldtype
:getfield
:invoke
⋮
:isdefined
:issubtype
:kwcall
:nfields
:setfield!
:svec
:throw
:tuple
:typeassert
:typeof

I think that it would be possible to change the names of those builtins to
__<name> instead of <name>, and then in boot.jl, have the julian
definitions like <name>(args::types) = __<name>(args). So it would be
possible to extend such functions.
