Re: [Yaml-core] Why is foo: 1:2:3:4 an integer in yaml?

[Ingy d. N. <in...@in...>]

The python one is 1*60^3+2*60^2+3*60^1+4*60^0. Not sure about the Ruby one.
Perl would be the string '1:2:3:4'.

Welcome to the sexagesimal debacle of YAML implicit typing.
Specifically: [-+]?[1-9][0-9_]*(:[0-5]?[0-9])+
*# (base 60)*

Back in 2005ish we made up a bunch of types that unquoted scalars should be
cast to: http://yaml.org/type/

Later we (yaml core) decided that the default type resolution should match
JSON, but we never took down the type info. This has led to much bugginess
in scalar typing.

Hopefully we can get schema related guidelines locked down in YAML 1.3.
