I had tried to render the expression "invalid at computed-value time" into very understandable Russian.
It was rendered as "недопустимое значение" by myself, and so trimmed in a way that retains no real essentials. Really, I do not want to say "invalid value".
Let me explain it. It comes from computation. For example, I have a function, an input value and a conditional statement that defines if an output value returned by the function is acceptable. I do not know if the input value is valid to be taken as an input because it depends on what the output value is. Later, at computation time the output—the computed value—proves to be unacceptable, so the input value is invalid at computed-value time.
What is accurate rendering of the expression so it never need to be explained in order to be properly understood?
