constant 'pi' in model code doesn't work

[perrydv]

This must have once worked?

m <- nimbleModel(
  nimbleCode({my_pi <- pi})
)
m$my_pi #NA

Please see issue #92 - we had a lengthy discussion of this and decided not to handle it natively.

[perrydv]

Oh yeah, thanks. I guess we could error-trap it?

[danielturek]

Error trap in what manner?

One logical perspective is that pi should be a valid variable name in models (for stochastic, or RHS nodes) as in this example, without throwing in error.

[danielturek]

Maybe, perhaps, issuing a Note, at the time of model building:

[Note]: The use of "pi" as a variable name is detected in model.
This will represent a model variable the same as any other name,
and will not have any implied connection with the numerical value 3.14159....

[paciorek]

Yes, I was imagining a short note if we detect pi in a model and it was not set as part of data, constants, or inits.

[paciorek]

Should make sure it's only RHS.
