Rainer Schuetze <r.sagita...@gmx.de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |r.sagita...@gmx.de --- Comment #4 from Rainer Schuetze <r.sagita...@gmx.de> --- I don't think this is a regression from 0.44-b2, nothing has chnaged in the semantic engine. Instead, it very much depends on where you trigger the completion box and what imports are in that file. You are hitting an endless loop when the semantic engine tries to evaluate std.algorithm.setops.cartesianProduct for UFCS expansion. You might want to disable UFCS expansions in the Intellisense options as it will also improve the speed of the completion box. --
