So why use := ? Some people prefer pre-fixing affectation, and as I

value".
I like "put value into variable", but would much prefer ":=" to "="
(which looks like equality) or "let variable = value" (which looks like
the variable does not change over scope). To me "let" has a particular
mathematical meaning and its usage in basic is grating.
The language Savvy used "put value into variable".
I am not familiar with "affectation" for assignment. This is probably
a hole in my knowledge. Perhaps it is distinct in some way so
"assignment" can be more general or more specific; perhaps it is
borrowed from the French.
One main advantage of "put value into variable" is that it emphasizes
the container model. On big problem is that terms like RHS (value) and
LHS (variable) get confusing.
