parse error on input '='

[mashaal]

I'm running into a strange error with neovim on manjaro. Standard tidal code works fine, but anytime I try to run a variable or custom function with an equal sign, I run into compile errors...

fill e x = every e (fix (ply 3) (s x))

WontCompile
error: parse error on input '='

I have VSCode installed on this machine as well, and when using the Tidal extension, the above code is working as expected. Could this be something with either the Tidal startup in this package or my neovim settings?
