getproperty type piracy

[mohamed82008]

Hi,

I would like to draw your attention to a type piracy that Catlab has in its definition of getproperty. This is causing a slowdown in surprising ways in Julia. Ref: JuliaLang/julia#39534

Thanks for reporting this. We'll look into fixing it.

I did not actually realize that this counts as type piracy, but if it's causing problems, it should be fixed.

@olynch, we should address this. I suggest that we just eliminate the getproperty overrides for C-set types and replace them with accessor functions, e.g., CD.ob would become ob(CD). Definitely no type piracy there since we own those functions.
