Scriptol/While Let

Common syntax
while x < 5 print x x + 1 /while

To increment a variable, Scriptol uses x + 1. This could not work in C and other languages.

Infinite loop in C
The C and C-like languages (C++, Java, C#) leads easily into infinite loop. Here hare two simple examples.

while(x < 5); {  printf("%d\n", x); x += 1: }

Perhaps you have instantaneously noticed it (and perhaps no), but the construct is bad, due to the semi-colon after the condition!

Another example without the misplaced semi-colon:

while(x < 10) {  printf("%d\n", x); if(x = 5) continue; ... some statements ... x += 1; }
