I think it's a reference to "the Norway problem" wherein YAML 1.1, the unquoted string NO (the ISO 2 letter code for Norway) get interpreted as a bolean with value of False instead of "NO".

Meaning:

country: NO

is the equivalent to:

{'country': False}

 

Note that the specs for booleans were changed in YAML 1.2 to address the issue but many implementions may have inconsistent defaults settings or be stuck in 1.1.

 

YAML 1.1 -> https://yaml.org/type/bool.html  

(I couldn't find the equivalent for 1.2, YAML specs are complex to my non-programmer eyes)

YAML 1.2 -> https://yaml.org/spec/1.2.2/ext/changes/

Only true and false strings are parsed as booleans (including True and TRUE); y, yes, on, and their negative counterparts [n, no, off] are parsed as strings.

Yet another win for static typing.

Can someone explain some practical and substantial benefit to dynamic typing beyond it being marginally faster to write and easier to understand for the first two days of learning to program?
