There is another interesting hack, which comes about as an implementation
detail of Perl, but I don't know whether or not it qualifies.
I'm not planning to enter, since I always do embarassingly badly at
these things - I'm afraid I have too much practice writing clear and
readable code that I find it difficult to get into the spirit of things ;-) -
but I guess this would be a pretty useful idiom:
perl -aln0 -F"\n" -e ...
(Stick an entire file into @F, a line per element.)
However, if you write it as a program, instead of
#!/usr/bin/perl -aln0 -F"\n"
...
you can say
#!/usr/bin/perl -aln0 -F
...
because the character after -F happens to be a newline. Handy, that, eh?
