[New Feature] Extend } with }.. to allow direct gap insertions - direct insertion into arrays (9) 1}..1 2 3 4 5 --- 1 9 2 3 1 4 5 #234

one current approach for insertion.
z=.1 0 1 #^:_1 'ab'
]z=.'a' (1)}z
'aab'

shorter:
'a' (1)} (1 0 1 #^:_1 'ab') --- 'aab'

for more direct gap insertion with }..

'a' (1)}.. 'ab' --- 'aab'

with }.. or..... some other glyph.

Uiua uses glyph completion (Mnemonic glyph completion from ASCII sequences) and that enables new glyphs. No need for a new keyboard or labels. Perhaps '⋔' for gap insertion. Maybe direct gap insertion allows in-place.
