Simple Function Decorator Sample Snippet

[Mark H Harris]

hi folks, I've come up with a simple snippet that intends to explain the
concept of decorations without an article (for on app help), while being
succinct and concise, while not being overly complicated.

Does this work? I have another one coming for args, similar, if this
works... comments appreciated. thanks.

I don't think that this idea is original to you I'm pretty sure many
people have come up with the idea of a decorator that just announces when
it runs and when it is called. I know I have

People keep independently inventing this because it's an obvious, and
easy to understand, example. Nicely done.

I tried to run your code, but every line is quoted with a > which causes
a syntax error. Was there a reason you quoted the snippet?

oh, absolutely... every piece of that thing comes from somebody
(about six somebodies to be exact) what makes it unique is that its
compressed, in the right order (I think), and 'without' extraneous
gibberish that confuses the whole dang thing.

Its obvious until you get to the @charater. In fact its taken so
obviously by *everyone* that no one actually gets it explained without
eight pages or twelve steps of something until its all confused.

Yes, because depending on your interface the code can get mangled (the
indentation thing breaks). the quoted paste seems to avoid this mostly
with the downside that the quote characters need to be striped from the
py file. <sorry> by the way, any suggestions are welcome regarding
that too... there doesn't really seem to be a good way to share code on
the group consistently.
