# Example program showing that a function call can be 'paused' multiple times,
# creating different continuation values.
#
# To run:
# $ git clone https://github.com/akkartik/mu
# $ cd mu
# $ ./mu continuation3.mu
#
# Expected output:
# caller 0
# callee 0
# caller 1
# callee 1
# caller 2
# callee 2
