* Positional perl expressions (similar to {2}) are given as {=2 perl expression=} where 2 is the position.
* One small backwards incompatability: {1}_{2} will replace {2} with the empty string if there is only one argument. Previously {2} would have been left untouched.
* Replacement strings can be defined using --rpl. E.g. parallel --rpl '{.gz} s/\.gz$//' echo {.gz} ::: *.gz
* The parenthesis around {= perl expression =} can be changed with --parens.
* --tmux will direct the output to a tmux session instead of files.
* --tmux will direct the output to a tmux session instead of files. Each running jobs will be in its own window.
