I've been writing code for pay for more than 20 years and will forget basic syntax and keywords for a language I wrote hundreds of lines in yesterday without other code to crib off of, IDE assistance, and/or reference material (google, whatever). Like, I'll forget if it's "else if" or "elsif" or "elseif" or "elif" or whatever. Or I'll mix up how to access hash/list members. How to designate a constructor. Stuff like that.
