5. String Formatting
String are denoted by a pair of " and may span multiple lines.
5.1. Interpolation
Note
String Interpolation is not yet supported.
In order to insert values into strings jam supports a concept called string

cast to a String and inserted into the string.

# This will print out "My name is Harold"
puts("My name is #{name}")
