# In the tutorial https://www.tutorialspoint.com/ruby/ruby_syntax.htm
# there is a quote:

# Whitespace characters such as spaces and tabs are generally ignored in Ruby code,
# except when they appear in strings. Sometimes, however, they are used to interpret
# ambiguous statements. Interpretations of this sort produce warnings when the -w
# option is enabled.
# Example:
# a + b is interpreted as a+b ( Here a is a local variable)
# a  +b is interpreted as a(+b) ( Here a is a method call)

# However, this program prints out "3\n3\n" instead of crashing when trying to apply
# a to the value positive b. So there must be more to it than that, right?

a = 1
b = 2
c = a + b
# I do get a warning for this next line, however it parses it the same as the previous.
d = a +b
puts c
puts d
