bool checkAccess(AggregateDeclaration ad, Loc loc, Scope* sc, Dsymbol smember);

Do access check for member of this class, this class being the type of the 'this' pointer used to access smember. Returns true if the member is not accessible.

bool checkAccess(Loc loc, Scope* sc, Expression e, Declaration d);

Check access to d for expression e.d Returns true if the declaration is not accessible.

bool checkAccess(Loc loc, Scope* sc, Package p);

Check access to package/module p from scope sc.

Parameters:

Loc `loc`	source location for issued error message
Scope* `sc`	scope from which to access to a fully qualified package name
Package `p`	the package/module to check access for

Returns:

true if the package is not accessible.

Because a global symbol table tree is used for imported packages/modules, access to them needs to be checked based on the imports in the scope chain (see https://issues.dlang.org/show_bug.cgi?id=313).

bool symbolIsVisible(Module mod, Dsymbol s);

Check whether symbols s is visible in mod.

Parameters:

Module `mod`	lookup origin
Dsymbol `s`	symbol to check for visibility

Returns:

true if s is visible in mod

bool symbolIsVisible(Dsymbol origin, Dsymbol s);

Same as above, but determines the lookup module from symbols origin.

bool symbolIsVisible(Scope* sc, Dsymbol s);

Same as above but also checks for protected symbols visible from scope sc. Used for qualified name lookup.

Parameters:

Scope* `sc`	lookup scope
Dsymbol `s`	symbol to check for visibility

Returns:

true if s is visible by origin

bool checkSymbolAccess(Scope* sc, Dsymbol s);

Check if a symbol is visible from a given scope without taking into account the most visible overload.

Parameters:

Scope* `sc`	lookup scope
Dsymbol `s`	symbol to check for visibility

Returns:

true if s is visible by origin

Dsymbol mostVisibleOverload(Dsymbol s, Module mod = null);

Use the most visible overload to check visibility. Later perform an access check on the resolved overload. This function is similar to overloadApply, but doesn't recurse nor resolve aliases because protection/visibility is an attribute of the alias not the aliasee.
