Hello all,
I'm writing a simple language where functions is a feature. To do this I
need to somehow catch the tree of expressions/statements and execute it with
the parameter(s) when it's needed. However, is it possible to create those
trees when walking over the AST? Let's say I have this in the tree:
^(FUNC_DECL type ID formalParams? block)
Is it possible to get the tree of the block? I only found this possible to
do when building the AST (using $block.tree) but I can't seem to do this
when walking over the AST.
Thanks,
William van Doorn
