Concatenation

TSL denotes the string concatenation operator by ―..‖ (two dots). If any of its operands is a
number, TSL converts that number to a string:
print("Hello ".."World")
print(0 .. 1)
Output of code above:
Hello World
01

Branching

TSL uses the ―if‖ keyword to do conditional branching.

Zero IS true! This is a contrast to C
where
0 evaluates false. In TSL, ―nil‖ is false
and everything else is true.
This is if expression 1.
