[Live] scalar type coercion when hydrating

[kbond]

If a component property's type-hint is int and you try to hydrate with '', you get an error. I propose we automatically cast simple, scalar types:

• int: '' or ' ' => 0
• float: '' or ' ' => 0.0
• bool: '' or ' ' => false
• ?int: '' or ' ' => null
• ?float: '' or ' ' => null
• ?bool: '' or ' ' => null

How to handle?

• int: 'apple'?
