Re: prevent mitosis from partitioning (filter) function arguments

UPDATE:

I solved this for now by hardcoding in opt_mitosis a bailout condition for that specific function.

Wouldn't it be useful to use a function marker for this, along the lines of {inline|unsafe} markers?

Something like:

blocking command myfunction(...);

and then disable mitosis for all blocking functions (i.e. functions that need to consume their whole input)?

On the same topic, I also noticed that mitosis currently isn't disabled on unsafe functions. Is that correct? If a function is unsafe, calling it multiple times could be... .. well ... unsafe? ;-)

Hmmm, normally ‘unsafe’ is the keyword you need. Doesn’t it work for your function? I took a look at the impl. of quantile, because its input is surely not partitioned. but I can’t quickly find how that requirement is past to mitosis...

How can I prevent mitosis from partitioning its inputs?
