Re: [julia-users] Re: Debug printing a “value” and its “symbol”

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?
