• The println builtin is now known as echo.

• The == builtin now compares numbers -- == 1 1.0 is true, while == a a throws an exception. To compare strings, use ==s. It is part of a family of new builtins for comparing strings, <s, <=s, ==s, !=s, >s and >=s.

• The is builtin is the new generic (shallow) equality predicate. The deep equality predicate deepeq is now known simply as eq.

• Automatic use'ing has been removed. All modules must be used before use.

# Usage:
# Invoke this script with the current command line, one argument per word:
#
# bash get-completion.bash pacman -S x
#
# Exits with 1 if no completer has been found.
#
# To use this as the default completion in elvish, put the following in ~/.elvish/rc.elv:
# le:completer['']={ bash /path/to/get-completion.bash $@ }
