CheckBox() not working in session after coding error

[jmontalvo94]

Hi!

I was using CheckBox() from PlutoUI but I accidentally wrote $(@bind cost1 CheckBox(), default=true) instead of $(@bind cost1 CheckBox(default=true)) and apparently you can't use CheckBoxes anymore in that session (even if removing that line of code in the cell) so I had to restart the session. The error is

┌ Warning: unknow use of `=`. Assignee is unrecognised.
│   ex = :(CheckBox())
└ @ Pluto.ExpressionExplorer ~/.julia/packages/Pluto/upwxH/src/analysis/ExpressionExplorer.jl:160

This seems to be an issue with ExpressionExplorer:

This code:

julia> f(), g() = true, false
(true, false)

julia> f()
true

julia> g()
false

julia> f
f (generic function with 1 method)

is legal, but our expression explorer does not work:

julia> Pluto.ExpressionExplorer.compute_symbolreferences(:(f(), g() = true, false))
┌ Warning: unknown use of `=`. Assignee is unrecognised.
