Confusing error for setindex! on VarInfo

[phipsgabler]

Is the following behaviour really intended?

julia> vi
/=======================================================================
| VarInfo
|-----------------------------------------------------------------------
| Varnames  :   ["p"]
| Range     :   UnitRange{Int64}[1:1]
| Vals      :   Real[0.9574412442107834]
| GIDs      :   Set{DynamicPPL.Selector}[Set([])]
| Orders    :   [0]
| Logp      :   -0.043490923558696964
| #produce  :   1
| flags     :   Dict("del" => [0],"trans" => [0])
\=======================================================================


julia> vi[VarName{:p}("")]
0.9574412442107834

julia> vi[VarName{:p}("")] = 0.5   # why not allow this?
ERROR: ArgumentError: indexed assignment with a single value to many locations is not supported; perhaps use broadcasting `.=` instead?
