# Represents an inline argument in a step. Example:

# Given the message
# """
# I like
# Cucumber sandwich

#
# The text between the pair of <tt>"""</tt> is stored inside a DocString,
# which is yielded to the StepDefinition block as the last argument.

# The StepDefinition can then access the String via the #to_s method. In the
