Reading the code, there is also a `indent` option, i thought it accepted a 
boolean, but not, I find it very unintuitive:

dump(io::IO, x, n::Int, indent) = xdump(dump, io, x, n, indent)


julia> dump(:(1 + 1 * 3 - 4^7), 10, false)
Expr 
false  head: Symbol call
false  args: Array(Any,(3,))
false    1: Symbol -
false    2: Expr 
false      head: Symbol call
false      args: Array(Any,(3,))
false        1: Symbol +
false        2: Int32 1
false        3: Expr 
false          head: Symbol call
false          args: Array(Any,(3,))
false            1: Symbol *
false            2: Int32 1
false            3: Int32 3
false          typ: Any
false      typ: Any
false    3: Expr 
false      head: Symbol call
false      args: Array(Any,(3,))
false        1: Symbol ^
false        2: Int32 4
false        3: Int32 7
false      typ: Any
false  typ: Any

And once can't use this argument, as a keyword argument:

julia> dump(:(1 + 1 * 3 - 4^7), indent="--->")
ERROR: function dump does not accept keyword arguments

Keyword arguments are slow? Or why are the not used that much throughout 
the API?
