Small fix and optimization

• Report mismatched reference error correctly
• Scan scopes via iteration instead of tail recursion

v0.2.3...v0.2.4

Make user-defined validators run in their definition scope

• [FIX] Run user-defined validators in their definition scope
• Scope refactoring: use a scope chain in place of a scope stack

v0.2.2...v0.2.3

Embedded references and Golang style union types

• Support union types
• Support embedded references for objects and arrays
• Support deep references to variable properties
• Remove type options (embedded references make it useless)
• Support backward references inside scope definition
• Throw/catch errors only if necessary (no useless stacktrace creation)
• Some fixes and performance improvements

v0.2.1...v0.2.2

v0.2.1 - Say hello to deep equal

• Add deep comparison capability to equals validator
• Add signature (info with name and argument descriptors) to all validators
• Add support for non referenceable arguments like scope in def
• Fix missing support for references in if, alter and onError validators
• Signature of alter has changed
• Remove non standard isDate validator
• Now null is allowed for type any
• Improve error checking
• Standardize tests for higher coverage

v0.2.0...v0.2.1

v0.2.0 - It's all about references

• New capability to reference paths, constants and validators
• New branch validator def to create a scope for constants and validators reachable by the child and all its descendants via references
• The signature of branch validator call has changed

v0.1.3...v0.2.0

v0.1.3

• Improve argument checking for bridged leaf validators cf993e6
• Optimize bridged validators that support any additional non-string type 8b07d99
