  28. def transform (tree: Tree): Tree

    Perform the following transformations:

    Perform the following transformations:

    • for a lazy accessor inside a method, make it check the initialization bitmap
    • for all methods, add enough int vars to allow one flag per lazy local value
    • blocks in template bodies behave almost like methods. A single bitmaps section is added in the first block, for all lazy values defined in such blocks.
    • remove ACCESSOR flags: accessors in traits are not statically implemented, but moved to the host class. local lazy values should be statically implemented.
