PowerShell yet again proves itself to be an enlightened language:

    PS> ${Valid characters for an identifier? Eh, ¯\_(ツ)_/¯ whatever (`}) you want.} = $True
    PS> ${Valid characters for an identifier? Eh, ¯\_(ツ)_/¯ whatever (`}) you want.}
    True

Jesting aside, I have actually used that syntax before to prefix variable names with '&' and '@' to differentiate between virtual and physical addresses in some code for patching a binary.
