$a=@"n'"'n"@' (#2913)
The tokenizer did multiple scans the script line to get tokens. Before the fix the tokenizer on the first pass examined that string as double-quoted (Expandable) string not as here string, figured the average double quotation mark as a closing and then starting with the single quotation mark continued processing the line as single-quoted string which had no closing single quotation mark. The fix is to stop the first scan pass after getting '=' (assume assignment-expression '$a=' for next pass).
PowerShell
Welcome to the PowerShell GitHub Community! PowerShell is a cross-platform (Windows, Linux, and macOS) automation and configuration tool/framework that works well with your existing tools and is optimized for dealing with structured data (e.g. JSON, CSV, XML, etc.), REST APIs, and object models. It includes a command-line shell, an associated scripting language and a framework for processing cmdlets.

Downloading the Source Code
The PowerShell repository has a number of other repositories embedded as submodules.
To make things easy, you can just clone recursively:
git clone --recursive https://github.com/PowerShell/PowerShell.git
If you already cloned but forgot to use --recursive, you can update submodules manually:
git submodule update --init
See working with the PowerShell repository for more information.
