Implementation of Placeholder Interpolation
The message MAY contain placeholders which implementors MAY replace with values from the context array.
Placeholder names MUST correspond to keys in the context array.

@param string $message or an object with a __toString() method
@param array $context replacement values for placeholders
@return bool
