Using meta-variants shouldn't effect normal execution

[cpsievert]

Currently we're expanding !! in normal execution, is that still necessary?

library(shiny)
library(shinymeta)
library(dplyr)

ui <- fluidPage(
  selectInput("var", "Var", names(mtcars)),
  verbatimTextOutput("txt")
)

server <- function(input, output, session) {
  output$txt <- metaRender(renderPrint, {
    group_var <- sym(input$var)
    mtcars %>%
      group_by(!!group_var) %>%
      summarise(mean_mpg = mean(mpg))
  })
}

shinyApp(ui, server)

Error in enquo: object 'group_var' not found

Or maybe expansion is needed, because without it, code that you write that you intend to work for meta-execution might not work for normal execution?
