Is it necessary to have the Boolean keyword? Wouldn't just surrounding an assignment operation be enough to evaluate it as an expression?

May be, but it will be much clearer like that.

I think no. If you have far indented source code, a Keyword (e.g. Boolean) moves the expression to the right out of the visible part of the editor window. The source code is worse readable through this.

Logic / boolean expressions shouldn't have any keyword.

At ambiguous expressions I want a mainly logical interpretation opposite an assignment interpretation.

Example:

Code: Select all

a = b = c
;
; if b = c then a = #True else a = #False

Logic expressions should be allowed in mathematical expressions.

Example:

Code: Select all

a = 4 + 3 * (b = c)
;
; if b = c then a = 7 else a = 4

A short keyword (e.g. LET or ALL) should make a multi assingnment possible.

Example:

Code: Select all

LET a, b, c, d, e = x * 10
;
; a = x * 10 : b = x * 10 : c = x * 10 : d = x * 10 : e = x * 10

LET a, b, c, d, e = x = y
; 
; if x = y then a, b, c, d, e are #True else a, b, c, d, e are #False

Without "LET" keyword it would be clear also.

Greetings.
