Alternative to procedure? (in Scheme)

[Oscar Finnsson]

Hi,

is there something like Schemes "procedure?" in Nu that can check if a variable is a procedure/lambda/do/NuBlock?

I'm using 

    (function do? (v) (send v isKindOfClass:(NuBlock class)))

but not sure if this is robust and if there is build in functionality for this already.

Regards,

Oscar

Hi Oscar,

I haven't created anything else - and I'm not aware of any other approaches. What you've shown should be fine because functions and lambda expressions are all internally represented as NuBlock instances.
