pure @trusted auto _d_HookTraceImpl(T, alias Hook, string errorMessage)(string file, int line, string funcname, Parameters!Hook parameters);

TraceGC wrapper around runtime hook Hook.

Parameters:

T	Type of hook to report to accumulate
Hook	The hook to wrap

string file	File that called _d_HookTraceImpl
int line	Line inside of file that called _d_HookTraceImpl
string funcname	Function that called _d_HookTraceImpl
Parameters!Hook parameters	Parameters that will be used to call Hook

Bugs:

This function template needs be between the compiler and a much older runtime hook that bypassed safety, purity, and throwabilty checks. To prevent breaking existing code, this function template is temporarily declared @trusted pure until the implementation can be brought up to modern D expectations.
