Types mapping
The rules in the table below are used to convert between yaml and factor objects. They are based on http://www.yaml.org/spec/1.2/spec.html, section "10.3. Core Schema" and http://yaml.org/type/, adapted to factor's conventions.

yaml	factor
scalars
!!null	f
!!bool	boolean
!!int	integer
!!float	float
!!str	string
!!binary	byte-array
!!timestamp	timestamp
sequences
!!seq	array
!!omap	linked-assoc
!!pairs	Association lists
mappings
!!map	hashtable
!!set	hash-set
special keys
!!merge	yaml-merge
!!value	yaml-value

YAML to Factor Round Tripping
The following YAML types are not preserved:

•	!!null -> boolean -> !!bool
•	!!pairs -> Association lists -> !!seq

Factor to YAML Round Tripping
The following Factor types are not preserved, unless another type has precedence:

•	assoc -> !!map -> hashtable
•	set -> !!set -> hash-set
•	sequence -> !!seq -> array

Examples of type precedence which preserves type: byte-array over sequence.
