Hello JastAdd developers,


Is the overhead for declaring an attribute as 'lazy' big?

( I guess that the overhead is caused to the amount of memory use. )

Why should we declare an attribute as lazy explicitly if lazy attributes are
beneficial in efficient calculation?

Why isn't 'lazy' the default?


Anyway, the keyword 'lazy' seems to be rather misleading.

Every attribute of JastAdd nodes is lazy in that it is calculated only when

I believe that 'cached' is a better word.

Am I understanding correctly?
