@parameters and @variables are malfunctioning

[filipepfarias]

I've been trying this code of the documentation recently but stopped working:

julia> rs = @reaction_network begin
           @parameters A B
           A, ∅ → X
           1, 2X + Y → 3X
           B, X → Y
           1, X → ∅
       end


ERROR: LoadError: Malformed reaction line: @parameters A B
Stacktrace:

in expression starting at REPL[1]:1

Am I doing something wrong?

BTW, I'm also trying to define time-dependent rates as functions. Was it suppose to work defining as @variable? Because for me it is presenting the same error as above.

Thanks.

Fixed by updating 12.3.2 -> 13.3.0
