TypeShade
SD0013
Core code
no active builder
No "use typeshade" program on this site raises this code, so the page has no example. The fn() builder builds the IR directly and reaches the check at the lines under Source.
The registry text and every compiler message on these pages are the compiler's own English.
How to fix it
The registry's hint: call Let/Var/If/Loop/… inside an fn / If / Loop body
