No, you miss my point. Let me put it this way: You're trading one type
of discoverability for another.
With type helpers, it becomes easy to discover that I can type
x.<Ctrl-Space> and immediately see ToString. But I'll never learn of
Format(), Trim(), etc. this way.
With IntToStr, the initial discoverability is hard, since I need to know
about IntToStr in the first place. But when I <Ctrl-Click> on IntToStr,
I immediately see Format(), Trim(), AdjustLineBreaks(), etc.
