@equations not seeing parameters defined outside the @reaction_network macro

[vyudu]

This currently throws an UndefVarError for E:

@parameters E F
@reaction_network begin
    @equations D(A) ~ E + F
end

Is this expected?

[isaacsas]

This needs to be

@reaction_network begin
    @parameters E F
    @equations D(A) ~ E + F
end

or

@reaction_network begin
    @equations D(A) ~ $E + $F
end

Variables/species/parameters declared outside the DSL need to be interpolated into it.
