Right, e.g. ProxySpace.push could be a cause for this.

If ProxySpace.push has been evaluated,
the workaround assumes that the assignments

~bd = 
~mel =

have been done before that.

Following from Ron's explanation, it is also important to be aware that
environmental variables are *non-globals*, but relative to the Environment.
However environmental variables in topEnvironment act like globals,
as the can be referenced by topEnvironment[...] from anywhere.
