QB64 Bug -- multiple plusses or minusses

C:\qb64>copy con test.bas
a=2
b=3
c=a+++++b
PRINT c
^Z

C:\qb64>compile test.bas

I am guessing that this is because C++ interprets the multiple pluses as increment operators:

c = a++ + ++b

(or,)

c = a + b + 1
a=a+1
b=b+1

Using minuses also produces an error:

C:\qb64>copy con test.bas
a=2
b=3
c=a-----b
PRINT c
^Z
