Handle print statements in non BEGIN/END blocks

[dspinellis]

They should be either prohibited, or, better, their outpout should be stored in memory or in temporary files and then serialized.

Hi @dspinellis, can you please provide me with such an example to test against.

Trivial implementation

awk '{print}' should fail with an error, while awk 'BEGIN{print "hello "} END {print "world"}' /dev/null should succeed printing hello world.

More sophisticated implementation

seq 1 10000 | awk '{print}' should output the same as seq 1 10000.

Since print is not parallelizable, shouldn't we restrict its use inside the action statement ?

[dspinellis]

This is the trivial implementation. The more sophisticated one involves storing its output and serializing it at the end of the program's operation.

I have implemented the trivial solution so far.
