Hi,
Tobbe, thanks for your helpful answer to my question about
associative arrays.
Here comes another (newbee) question. I must parse source code written
in some rather unstructured language, and I want to fill several
big AST's (abstract syntax trees) with the information that the
parser reads. Thus, the AST's are updated in a way that is not known
beforehand.
For the AST's I could take process dictionary variables, because these
can be updated destructively. However, for each small component that I
add to an AST, I would be oblighed to copy the whole AST, and add the
new component during this copy.
I am aware that this is an old issue for functional languages, and I am
shure that a nice pattern exists how to solve this in Erlang.
Kind regards,
Wouter Boeke
