1. Nested functions should inherit constants and static locals from
parent scopes, but not automatic local variables. At the moment the
former works, but when trying to (incorrectly) use a local variable
from an outer scope in an inner function, the compiler crashes:
example :: () {
x := 42;
x′ :: 69;
static x″ := 420;
foo :: () int { return x; } /* not fine; breaks */
bar :: () int { return x′; } /* totally fine */
baz :: () int { return x″; } /* totally fine */
}
This is presumably due to the compiler maintaining a single tree of
scopes where a scope contains information for both constants and
variables. If this is indeed the cause, then there should most
probably be separate scope-trees; one which has scopes for constants,
and one which has scopes for variables.
2. Recursive functions crash the compiler.
foo :: () { return foo(); } /* breaks */
3. Variable shadowing breaks when you create a local variable with the
same name as the parent function, failing with a circular-dependency:
foo :: () { foo := 5; }
This is not an issue with nested functions:
foo :: () {
bar :: () { foo := 5; }
}
