A note on the convergence analysis of Laguerre approximations for analytic functions

In a recent paper (H. Wang, Math. Comp. 93, 2861-2884, 2024), Wang has presented a number of results concerning the convergence of approximations based on generalised Laguerre polynomials, claiming to have provided"the first rigorous proof of root-exponential convergence of Laguerre approximations for analytic function...
