T#

# A simple calculator program in T#.
# =================================
# Program notes:
# The :result: is a virtual variable that is used to refer to the output of the previous function.
# :variable_name: is used to refer to variables. This can also be used in strings.
# If you call a non-existant variable in a string, it will just return the name of the non-existant variable you called.
# The restart function restarts the program from the first line.
# The if function is used for boolean operations. Note that nested if functions are not allowed.
# The break function stops the program execution on the spot.
