Description
Example: a string in the form of 344455e6 will not be quoted by the Psych YAML parser as it is not matching the regex used by the YAML1.1 spec for floats, however a YAML 1.2 compliant parser will interpret the value as a float since the decimal point and sign is considered optional in YAML 1.2.

Research direction
Start by locating Psych's YAML scalar and numeric-resolution handling, then trace how the example 344455e6 is classified under the YAML 1.2 behavior described here. Add a regression test for this form and verify that the parser's result matches the intended string handling.
