Typing info for log function misses 2nd argument

[csemrau]

The optional log function is called with 2 arguments, the message and the level (although the level is always 'warn'). The typing information only declares the 1st argument:

tarn.js/lib/Pool.d.ts

Line 15 in 270a295

log?: (msg: string) => any;

Therefore, the example pool from README.md won't compile in TypeScript:

    log: (message, logLevel) => console.log(`${logLevel}: ${message}`),

Thanks for report. Yes looks like there is a bug. I'll fix and add test case for it when I get some spare time.
