Unexpected 1d/2d array method error message with unsupported keyword argument

[tkf]

I couldn't find any issue tracking this:

julia> identity([1 1]; unsupported = :keyword)
ERROR: MethodError: no method matching identity(::Array{Int64,2}; unsupported=:keyword)

You might have used a 2d row vector where a 1d column vector was required.
Note the difference between 1d column vector [1,2,3] and 2d row vector [1 2 3].
You can convert to a column vector with the vec() function.
Closest candidates are:
  identity(::Any) at operators.jl:511 got unsupported keyword argument "unsupported"

This seems to happen only with keyword arguments:

julia> identity([1 1], nothing)
ERROR: MethodError: no method matching identity(::Array{Int64,2}, ::Nothing)
Closest candidates are:
  identity(::Any) at operators.jl:511

this fix may be imperfect if somehow it was a 1d/2d method error && keywords are presented? But in that case I assume user can remove the unsupported keyword and then see the 1d/2d error, so this is fine.

Wow, that's a super quick fix :) Yeah, agree about that the user can remove the unsupported keyword argument.
