Why are generator-related symbols not exported?

[decipaliz]

hello! i'm sorry if this is inappropriate, i'm relatively new to common lisp

i was experimenting with this library and i found that defining new sources through (defmethod transduce ...) is quite cumbersome for some of the simpler sources, and instead something like a function that gets called repeatedly and its return value gets used is far more simple and clean. seems like there's a type for these types of sources in the library and it's called a generator

what i wasn't very pleased with is the fact that all generator-related symbols are internal, and accessing them with :: doesn't seem conventional to me

are even the simpler sources supposed to be defined with (defmethod transduce ...), or am i missing some convenience utility that covers this? if neither, maybe these symbols could be exported?

Hi there. generator is intended for simple, potentially infinite sources like ints and repeat. For more substantial sources that involve a custom type, it's assumed that the user will write their own (defmethod transduce ...). Here's an example of how to do that for a "third party" type:

Hi there, any thoughts on this?
