Nick Coghlan a écrit :
Implementing __with__ instead would give the CM complete control over
whether or not to execute the block.
please note, however, that this is an important change in the semantics of the
with statement. As things are today, barring exceptional circunstances, the body
of the with statement *will* be executed immediately. This allows to forget
about the with statement when first reading code, as it doesn't change the
intent of the programmer. What Glyph is proposing is more akin to Ruby code blocks.
cheers,
Baptiste
