Delayed expansion of __FILE__ and __LINE__

Is it possible to delay the expansion of __FILE__ and __LINE__ such that I could pass the caller's context file/line to a macro?

!macro _Detail __FUNCTION __FILE __LINE msg

  DetailPrint "${__FUNCTION}() [${__FILE}:${__LINE}] ${msg}"

!macroend

!define Detail `!insertmacro _Detail __FUNCTION__ __FILE__ __LINE__`



;; ...

;; In some other file...



${Detail} "Message...."

I'd like for the detail message to use the file/line number where ${Detail} was actually expanded/"invoked". Is this possible, somehow, without my having to "${__FUNCTION__}" ... everywhere I use ${Detail}?

You have to use the dollar hack with NSIS 2 or Unicode escape in NSIS 3

!macro _Detail __FUNCTION __FILE __LINE msg

DetailPrint "${__FUNCTION}() [${__FILE}:${__LINE}] ${msg}"

!macroend


!define DOLLAR "$"
!define Detail `!insertmacro _Detail "${U+24}{__FUNCTION__}" "${U+24}{__FILE__}" ${DOLLAR}{__LINE__}`

Function/Section can probably be expanded inside the macro.
