More nim newbie woes, this time echo fmt Possible AOC2021 spoiler

[freeflow]

I've got day04 code than is now 'clean' in VSCode by changing from echo fmt to 
just echo. However I'm still seeing the compiler error out with 
    
    
    [Running] nim compile --verbosity:0 --hints:off --run [Running] nim compile 
--verbosity:0 --hints:off --run 
"c:\Users\*****\source\repos\AoC2021\Nim\Sources\Main.nim"
    C:\Users\*****\.choosenim\toolchains\nim-1.6.0\lib\core\macros.nim(533, 3) 
Error: undeclared identifier: 'BoardsAsNumbersrnalErrorFlag'
    candidates (edit distance, scope distance); see '--spellSuggest':

C:\Users\*****\.choosenim\toolchains\nim-1.6.0\lib\core\macros.nim(525, 6)]
    
    
    Run

Should I raise this as a compiler issue?
