Vim 7.4 shows errors on launch

[Spikatrix]

Launching Vim 7.4 gives me the following errors:

Error detected while processing function DiscordAsyncWrapper:
line    9:
E117: Unknown function: timer_info
E15: Invalid expression: timer_info(s:timer)
line   10:
E121: Undefined variable: info
E116: Invalid arguments for function len(info) == 1 && info[0]["paused"] == 0
E15: Invalid expression: len(info) == 1 && info[0]["paused"] == 0
Press ENTER or type command to continue

But the Discord RPC seems to be working even though I get those errors at launch. Worth mentioning that I get no such errors on Vim 8.2

The async features were introduced in Vim 8. Didn't count on Vim 7 still being used in the wild

... except it wasn't, because has("timers") has to be true for that to happen.

Vim 7.4 was the preinstalled vim that came with my Linux (Granted, I installed Linux about 1.5 years ago).

has("timers") does return true for both Vim 7.4 and 8.2

I know. My best guess is that parts of the timer API got implemented later, but I have no idea how to detect that. The documentation isn't very useful either (it just says the functions exist, but not when they were implemented :facepaw:)
