Parameter	Requirement	Description
`seq`	A model of Forward Sequence, `e == old_value` is a valid expression, convertible to `bool`, for each element `e` in `seq` with type convertible to `T`	Operation's argument
`old_value`	Any type	Value to replace
`new_value`	Any type	Replacement value

Expression =======

Expression >>>>>>> .merge-right.r57125 Semantics

replace(seq, old_value, new_value);

Return type: A model of Forward Sequence.

Semantics: Returns a new sequence with all the values of seq with new_value assigned to elements with the same type and equal to old_value.
