Description

Логика выражений типа M [0] :: M [1] = R [4] некорректна. Она должна означать:

M [0] = R [4];
M [1] = R [4]

Вот что написано в драфте Фредерикса:

<<<<<<<<<<<<<<<<<<<<<<
4.10 Concatenation of Values

The :: operator allows the concatenation of arbitrary expressions; it is de ned on the left side of
assignments, too (if the expressions denote memory locations only, of course). For example,
M [0] :: M [1] = R [4]
assigns the value of R [4] to the locations M [0] and M [1]. The order is the same as used in sequences
of locations, i.e., essentially unde ned.

Нужно найти решение.
