// WebAssembly.CompileError(message, fileName, lineNumber)

// The WebAssembly.CompileError() constructor creates a new WebAssembly
// CompileError object, which indicates an error during WebAssembly
// decoding or validation


// WebAssembly.LinkError(message, fileName, lineNumber)

// The WebAssembly.LinkError() constructor creates a new WebAssembly
// LinkError object, which indicates an error during module instantiation
// (besides traps from the start function).

// new WebAssembly.RuntimeError(message, fileName, lineNumber)

// The WebAssembly.RuntimeError() constructor creates a new WebAssembly
// RuntimeError object — the type that is thrown whenever WebAssembly
//  specifies a trap.
