Compiler implementation of the D programming language.

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);
Operator overload. Check for operator overload, if so, replace with function call. Return NULL if not an operator overload.
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
