bool isCommutative(TOK op);

Determine if operands of binary op can be reversed to fit operator overload.

Objects* opToArg(Scope* sc, TOK op);

Helper function to turn operator into template argument list

Expression op_overload(Expression e, Scope* sc, TOK* pop = null);

Operator overload. Check for operator overload, if so, replace with function call.

Parameters:
Expression e expression with operator
Scope* sc context
TOK* pop if not null, is set to the operator that was actually overloaded, which may not be e.op. Happens when operands are reversed to to match an overload
Returns:
null if not an operator overload, otherwise the lowered expression
Expression build_overload(ref const Loc loc, Scope* sc, Expression ethis, Expression earg, Dsymbol d);

Utility to build a function call out of this reference and argument.

Dsymbol search_function(ScopeDsymbol ad, Identifier funcid);

Search for function funcid in aggregate ad.

bool inferForeachAggregate(Scope* sc, bool isForeach, ref Expression feaggr, out Dsymbol sapply);

Figure out what is being foreach'd over by looking at the ForeachAggregate.

Parameters:
Scope* sc context
bool isForeach true for foreach, false for foreach_reverse
Expression feaggr ForeachAggregate
Dsymbol sapply set to function opApply/opApplyReverse, or delegate, or null. Overload resolution is not done.
Returns:
true if successfully figured it out; feaggr updated with semantic analysis. false for failed, which is an error.
bool inferApplyArgTypes(ForeachStatement fes, Scope* sc, ref Dsymbol sapply);

Given array of foreach parameters and an aggregate type, find best opApply overload, if any of the parameter types are missing, attempt to infer them from the aggregate type.

Parameters:
ForeachStatement fes the foreach statement
Scope* sc context
Dsymbol sapply null or opApply or delegate
Returns:
false for errors
