For the record, the perldoc for the "YAML" module starts with an example which shows the method Load using the here doc syntax to parse a string. I don't disagree that example complicates the explanation of how the Load command works, but it also clearly states in the "FUNCTIONAL USAGE" section...

Load(string-containing-a-YAML-stream)

    Turn YAML into Perl data. This is the opposite of Dump.
Just like Storable's thaw() function or the eval() function 
in relation to Data::Dumper. It parses a string containing a 
valid YAML stream into a list of Perl data structures.

It also says...

LoadFile(filepath)

    Reads the YAML stream from a file instead of a string.
